After all the great research provided here I located the "address" of this business.  It's a UPS Store in Mira Loma.  This is exactly what all the "Corona Scammers" were using to bilk people out of money and used similar practices.

I've already files a complaint with the IC3 and BBB.  Not that it matters but I like calling back with that info when I tell them where they can go.

Got a call from an "UNKNOWN" number yesterday while I was at work on my cell phone. I can't answer calls while I am at work, so I declined the call. The number then called me 4 more times in a row, and on the 4th call, finally left a message.  This message stated that he was "Brian Pierce" and there was some "legal matter" they wished to discuss with me, and he left a case number.

If I was not the nosy person I am, I would have called him back when I got off work, but it didn't 'sound' right.  This guy stammered and, of all things, in the middle of the name Brian Pierce, he said "UH"..  it was "Brian UH Pierce"..  So this was just a red flag in my book..  

They called my brothers number today.  They told him they had a subpoena and was attempting to serve it against me. I supposedly had two hours to return their call or I would be arrested.  

i saw your post because i too have been having this number call and harass my family members. I told my family not to give them any information as there are a lot of scams going on with these types of calls. i called the number they left and the name i got was colonial management which as far as i could find is some type of drug treatment company. they are not real debt collectors they do not follow debt collection laws. please go after them they scared my ex mother in law half to death with their illegal threats

855-319-9727 called my work and spoke with one of my managers pretending to be "officer David". He told my manager that they needed to serve me papers and that if I did not want to be served at work to call that number to schedule an appointment. When I called that number, there was no officer David or any other officer for that matter. He told me that there was a warrant out for my arrest and that they were authorized to take hostile measurements to reprimand me if I did not pay my fees. It is illegal and morally wrong to impersonate an officer and further more to threaten the lives of others even for a collection agency. I think this establishment should be stripped of their license and be held accountable for causing pain and suffering both mentally and physically by harassing innocent people. I think the California superior court should grant this establishment and every person associated with it right down to the secretary a maximum sentence at a federal prison.

Sorry this is so long, but I want to share in detail what happened to me just in case it could help someone else. This is the second scam attempt on me and if it wasn't for a detailed post I read from a while ago, not sure I would recognize some signs or know what to do.
I just received a phone call from a private number. When I answered a well-spoken woman proceeded to tell me that a third party company has been trying to serve me papers and wanted to confirm my address (which she already had). As she was confirming my address, I interrupted her and asked what this was all about, since I had no clue at all. She said she did not have that information and to call 855-319-9727 and gave me a case number and if I do not show up for court, the judge would proceed without me. I was scared.
So I gave the number a call and spoke with a "Scott" this is what he told me: Apparently for the last two weeks there have been many attempts to serve me papers, because I am being sued by Wells Fargo due to an overdrafted account back from 2008. I told "Scott" that, I am recently unemployed and I have been home for the last three weeks and no one has stopped by - RED FLAG 1. SIDENOTE: I live in a very small town, like there-are-no-stop-lights small town. Everyone knows everyone and if anyone was looking for me, not only would they give directions, people here would probably walk with you to my apartment.
Here's RED FLAG 2 - After I stated there has been no contact, he proceeded to verify that I was the 'right' person. He confirmed the last four of my social (which scares me that they have that) and my birthdate. He DID NOT confirm my address, which you would think he would do when I say I haven't been served. Also, because he knows the reason I haven't been served is because no one is trying to serve me.
He proceeds to tell me my account balance and that Wells Fargo is willing to settle for half by the end of this month, which is in like 2 days. I tell him I could do it only after I receive my income tax which would be sometime in late Feb. because at this point I'm still scared and haven't realized the red flags. He then tells me if I will give him my account information or a debit card number, he will mark my account and they would take the funds out at the end of Feb. and I said OK. Remember I was scared, and this happened so quickly. I thought I was going to jail. But right after I said OK I knew not to do it. At that same time "Scott" said he would put me on hold while I grabbed my card. It was during this hold that I realized this could be a scam and that I needed to look into this company and talk to my husband. When "Scott" came back I told him that my husband must've taken my card and therefore I will need to call him at work for the information and just call back later. He up to this point had been pleasant until I denied him my card number and he became short and snobby - RED FLAG 3.
Here's RED FLAG 4 - I asked for his direct number and he gave me 951-268-1404 - not sure, but shouldn't your direct line reflect your company number? And when I asked for the name of his company he said Enterprise. I said, OK, Enterprise.....Incorporated? He then said, No, Enterprise United Partners. Why he didn?t tell me the full company the first time, I don't know.
SIDENOTE: Now, I was so freaked out because I did have a Wells Fargo account that I overdrafted, however that was years and years ago, and I thought that was all behind me. I have since then 'grown-up' and have seen the error of my ways.
RED FLAG 5 - Right after this phone call I called Wells Fargo. I ended up speaking to someone in the Wells Fargo Overdraft/Debt Collection department. There they said they could not see any debts against me, which means Wells Fargo sold my debt. So how can Wells Fargo sue me if they no longer have my debt and it was sold to a collection agency and in the great state of North Dakota, by law, a collection agency CANNOT sue you!
RED FLAG 6 ? I found you guys. This board. I found that others have experienced the same thing.
My advice for anyone is DO NOT give out any information. Say you don?t have your checkbook or that you have to call them back. Try to remember your conversation and think. Do your research before doing business with anyone. Google is your friend.  
Sorry this is SO long!

Their name is Colonial Asset Management 12523 Limonite ave ste 440-395, Mira Loma CA 91752

They are Colonial Asset Management 12523 Limonite ave Ste 440-395, Mira Loma CA 91752. Their practices are obviously wrong.

They did the same thing to me. It is illegal and I am working to file a law suit against them. They are scammers that try to collect old debts that they bought from companies that either went out of business or have written the debt off. It is legal to do what they do but not legal to go about it the way they are going. They cannot arrest you. In fact, unless they go to court and do things the right way, it is harrassment.

My brother received a call  today from a "courier" saying they were outside my home address and I was not home and they needed to deliver a court summons. He was also given a case number and a phone number 855-319-9727 to call back..we didn't call the number back because it seems that this is all just a scam. The one credit card I had from years ago has been paid off for a while so I can't imagine why a "debt collector" would be looking for me.
Have any of you recently put up your resume on career builder.com or any other similar sites?

Thanks for any responses.

It absolutely is against the law to impersonate a police officer!  Did you call your local police department?  I would call them and report this to them.  And if the guy shows up again - call the cops!  More info here:

1-855-319-9727

My parents received a call from this number stating they were CM Legal services & had been looking to serve me papers & I needed to contact them within 2 hours.  They had my parents petrified!  This really irritates me that these people can try this crap!

scam!!!!!!!!!!!!!

First I received a call from an "UNKNOWN" number and was told they were trying to serve me a warrant.  Since I had no idea what they were talking about, they decided to 'delay' serving the warrant until I could call and find out what it was all about.  I was given the number 855-319-9727 to call with a "case number."  It's a bill collector.  I wasn't even the person they were looking for: same name, wrong SS # and DOB.  The debt was on a line of credit for $1000 that wasn't paid.  They are now asking for $5,000+ (lawyer fees, etc.).
