I get a call everyday from this number.  THey do not even let it ring long enough to go to Voicemail, much less them leaving me a voicemail.  

numerous calls, did not answer.  they do not leave a message

Yes,you can block those calls from T-mobile but First you need a call blocker App. I recommend "Extreme call blocker" cost is simply a one time $5.99 for life meaning unlimited updates, you can find it at https://play.google.com.  it has lots of features you can block the call, have it disconnect automatically,have it forward to you voice mail etc.

i have fun with mine, i set it up so it goes to my voice mail, after it reaches my voice mail it tells them "I'm sorry but the voice mail is full , Please try again later.
Later will never happen because the number is always blocked.. it pisses them off completely, They will try to call you by using another number. that other  number will get blocked too and so on.

Collection Agency - They get very nasty when they don't get what they want!

Love the reasoning Lol

I got a call from this number on my cell, when I returned the call a nice man named Joe informed me they were looking for a woman by the name Arian Luhan. I asked him to remove me from the list as I have had my cell number for 6 years. He SAID they would remove my number from the list.

The government just bailed out all of these financial institutions from going bust.  They invested in hyper risky investments, lost that bet, and the government gave them our tax payments to save them.  Hence, my debt is paid.  Quit calling.

Just received a call from this number and told them that I live there and then the individual start asking questions about address and social security number.  Gave them the wrong information and they apology, so they could not go any farther with whatever information that had about the person.

Anyone who is still working for a debt collector is the true deadbeat.  The smart folks are the ones who DEFAULT!!!!

Only a fool would pay back debts in an imploding economy.  Lets face it, the monetary system is a F'in scam and it's flat out busted.  All money is COUNTERFEITED into existence in the first place.  

DO YOU FOLKS UNDERSTAND THAT?????

that is illegal for them to contact neighbors etc on a collection of a neighbor. Be sure if you know who they r to let them know they might have to eat the bill and get some money back.

They just called and I didn't answer the number because I didn't recognize it. I had just watched a special on our local news about people you don't calling your cell and if you answer you are charged thousands of dollars a minute. Hey if someone wants to talk to me they will leave a message LOL

just got the call and they asked for my fiance and I told them there is no one by that name here

Yet another scum collection group.  These are retarded morons who can't get a REAL job.

got a call from this # and I didn't recognize it.  I answered it any way and the person asked for two people.  I said he had the wrong # and he said this isn't the___ residence.  I said no-goodby and hung up

Client Services, who is this ?

Hi Jami,
Forgot to add this to my previous reply to you.  My Caller ID showed "Client Services".  Sorry for these 2 replies.  I don't want to be branded as a stalker!!  However, when's the last time you checked under your bed, and/or the dark corners of you closet.... ; < (    Please don't check alone.

You are right.  Tried it today (4/5/2012) and got the same results you mentioned.  
Jami......You MAY be selected to receive $5.00/week for life.  Stand bye,bye!

I just got a call on my cell phone from this number.  The guy said I was given as a business associate by Linda Malquin and wanted to know if I had another number to reach her.  I told him twice that I didn't know a Linda Malquin.  He hung up.

These people called and left no voicemail. The funny thing is, I've had this number for about a year, and I know for a fact it's not on any debt list because it's an unused business line. They seem to be dialing at random to see who they can scare into paying.

These people are trying to collect a debt that was satisfied for half that was owed to the original company a year ago. They are like a pack of ambulance chasing lawyers. Debra's (I doubt Sherlock is her real last name)phone number is 1-877-288-0504 extension 5836.The phone number that this call was made from is 913-971-0331. GET YOUR FREAKING FACTS STRAIGHT BEFORE YOU HARASS PEOPLE!

I do answer all calls I receive on my land line phone.  If I do not answer phone, the message  goes to voice mail, then when I call out, I get a beep-beep letting me know I have a message. Then I must go to voice mail and cancel the message.  Best to pick up phone, drop phone in cradle hanging up on the caller!!!

say other than English ?  the call ID name is unknow ? I will not pick up any unknow call anymore

They called asking for Tammy! I told them they had the wrong number and hung up!

Client Services, Inc. It's a debt collector.

This number called me today at 11:21 1/27/2012, also 1/26/2012 twice, 1/23/2012. Same as the other reports of woman calling for someone, or "who lives by me"...Someone needs to FINE them for these actions!

As soon as I answered the phone a woman didn't even say hello, just said my first name. I said who is this, she said Naomi, I said from where, she said client services. I said what client ?  She said is this. My first name again)  I said, No, but what client, she hung up.   She called me an hour later on my cell, we went thru the same routine again, ending with her hanging up on me.

I received a call from this number asking for my boyfriend. This person not only found me but also every member of his family and called to try and track him down. Yes, it is a collection agency. Don't give them any information

got a call thats Unavailable on a new cell and no voice mail

Next time they call tell them, politely, that the next time they call you are going to turn their number over to your attorney for a possible harassment suit.  Worked like a charm for me.  When I first set up my phone number I was getting 3, 4 calls a week for people who apparently used to live here. Since I started the attorney threat I get no phone calls

Very questionable. I was getting calls to my cell phone from this number every day.  They finally left an 800 number, but I called back on the number they called from (not the 800 number), and they said they were trying to contact someone named Naomi who they claimed has an uncollected debt, but I've had this cell number for over 10 years, and I've never heard of the person they asked for. Then they asked for my name, which I refused to give them.
