this number belongs to M2 Revenue Group.  Because they ask so many questions so quickly, your address your ss your date of birth...all with a foreign accent. I will not verify any info to them.  Even if you call back...no american will answer the phone 19 calls in 1 day.  Turning them into Lemburg Law offices.

I'm in the same boat as everyone else. These b*****ds kept calling me for months....never left a message. I would answer....no one there. Finally the other day I answered and someone was there. (Yep thick accent) He had my name but then ask for my birthdate. I asked "what does this pertain to?"  He said "it's for security purposes?" I was like WTF...you called me? Then again I asked "what does this pertain to" He said "We won't be able to conduct this conversation w/o your birthdate." I said, "well it's not going to happen" He said "ok" and and hung up. I'm blowing a fuse if they call again!!!  

I  called back  it was a  guy with a thick accent   getinng tired of  it  they call on Fridays at 8 am    and a red flag  was asking  my my bith date I did not give it  and hang up .!

I have been dealing with this so called collection agency for well over 6 months now.   They call daily now!  In beginning I truly believed they were a legit debt collector.  But after months of at least trying to be nice to people I can't even understand on the phone.  Explaining circumstances that I realized I shouldn't need to explain.  The other day, I heard the woman's voice, heavily accented, and I cussed her out!  I was so angry!  I just now looked the number up to see if there were other complaints.  Not like me to do research.  Should have known better.

The company say that was my student debt collected. The person in the other side asked me my four last social security number. I give it, but was incorrect. I though that something fishy was happening.  I called my school, and they say that was scam.

Missed a call from this number.  Call back from a landline and "cannot" understand this heavily accented individual... The are from Mira???? They stated if they made a call to my number, they left a reference number... "They did not",  They ask for my cell phone number and I stated "No, I would not give them my number.  I ask again the company they were from; once again I cannot understand them and they ask again for my cell phone number.  Very aggravated, therefore, I ended the call.

I just received a phone call from someone wanting me to identify myself by telling them my date of birth. No other piece of information would do. It didn't help his case that his accent was so thick I could barely understand him and I had never heard of the company he was with (Miramar?). He mentioned a local anesthesia group I had done business with but stopped just short of saying he was with them. Just tell me your date of birth and I will tell you what this is about. Yeah, that's not going to happen. I called the anesthesia group and told them there was a scammer using their name.

Keep getting calls from this #. No message .
There is a device that allows these people to call from anywhere in the world and they enter in any # they want that shows up in caller ID. So, you never know where or whom is calling or their true return #.
They can even enter in your # as the caller ID and you know you aren't pea king yourself.

call rcvd in the AM  rt call PM was a man with heavy accent. asked if I got a missed call...said "YES"  asked who or what company they are calling me..did not understand a word....asked for DOB, ZIP code ...i said dont know who you are and I dont provide personal info...the heavy accent man just said THANK you and I just hang up and searched the number 877-523-1278 and found this....DON'T FALL FOR IT...IF IT IS IMPORTANT MATTER THEY WILL CONTACT YOU BY MAIL AS WELL...I AM SURE ;)

Keeps calling starting early but never leaves a message.

Are you absolutely sure your money is going to an actual debt?  If you have an actual debt are you sure they are really the collecting agency for the medical facility/service?  
I am pretty sure these folks are scammers.  Be careful.

I get a call from 8775231278 every time my daughter calls or texts me only.  No one has ever left a message or called at any other time.  Weird, right?  So I blocked the number.  Still get a notice that they called though.
So I finally called back and got only a message saying it was an overseas number and out of my calling area.  
Then I did a reverse number look-up on several sites and have only been able to find anything about the number on two sites.  
Both sites ID this number as belonging to Meri-Med Revenue Group, an anesthesia related debt collector.  
I don't have any anesthesia related debts and neither does my daughter.
I contacted my cell phone service carrier and they told me to contact this number from a land line and request that they remove me from their list because by law if you request this they have to do it.  
This feels like a scam to me.  Calling them on a land line or any other line seems like a good way to open a door I don't want to open.  Just ignore these jerks.

I finally answered today.  Asked for my date of birth to verify who I was in reference to a business matter.  If you have my name and phone number you know who I am.  I said I did not give personal info over the phone.  They said they needed it to verify to discuss this business matter.  They don't identify themselves just keep asking for dob information.  I don't know who this is, but they are annoying.

Keep calling and leave no message.

I receive a call from this number at least twice a day everyday. They never leave a message.

call everyday when answer they hang up.

This number 877-523-1378 is from Miramed Revenue Group.  They are a medical collection agency and I paid them a partial payment, now they're bugging me for the other half.  I never answer calls from people of whom I'm not familiar with so I will never talk to them on the phone.  When I get the money, I'll just pay the bill and that's all I will do.

This is fraud at it's best. They call everyday saying it is a private matter and asks for my birth date. I feel sorry if anyone falls for this. They are trying to steal id's! Tell anyone you know - don't ever give any information over the phone!!!

Had numerous "hang-up" calls as described.  Finally, spoke to the guy with the heavy accent who wanted to speak with a person at my number a "confidential matter"  using the name of a family member. Wouldn't say anything more about it.  He was from Miramad Revenue Group which he claims if located in IL.  So I gave him a hard time until I go bored with it and hung up.  Maybe that'll keep 'em from calling again.

Received a call from this number during AM hours. Answered & the person with heavy accent said it was a 'confidential call' therefore to continue he first needed my birthdate.  That was a red flag. I asked if it was confidential then we should continue, he insisted on my birthday. I hung up & they have not called back, YET!

constant calls from this number, finally answered and was a man with heavy accent..with name "chris Nelson"  doesn't sound American  with that accent to me.  Tried to get my date of birth, address and kept telling me it was a private business matter....what a scam of some sort.  Becareful!!

I keep getting calls from this phone number.  I answered it and a guy was insistent on telling me that the call was in reference to a business matTER. Hung up on him

Caller would not identify themselves. I am on the do not call list.

They called me so many times asking me about settling bills, I told them send the bill and let me verify it and even I gave them my address again and again, but they haven't send the invoice. Instead, they are asking me to pay online. It is amazing, how on earth they expect I will give them my information with out reviewing the invoice.

wont stop calling me. doesnt leave message. very annoying

I make a point of not answering numbers I'm not familiar with, and my outgoing v-mail message makes that clear - if people want me to return their call, I will, IF they leave a message with pertinent details. This number did not do that, so - TS, Eliot!

its getting annoying. whom ever it is doesn't leave a message.

Marimim or something to that effect. Calls 2 or 3 times daily looking for someone I've never heard of. Upon telling them that they're calling a 13yr old childs phone, this guy with a heavy accent asks my name. I told him he either stops calling my child or I'm turning it over to authorities.

They call once or twice daily. I know the number calling, so I don't pick -up. The time I did pick-up they hung up and call back moments later which I didn't answer either. They'll quit calling for a week or so and start back-up... .
