They use "phone spoofing" which allows them to use any area code and phone number to make you think they are local.  You can get a phone spoofing calling card for about $5.00 on the internet and see for yourself.

These people called me on friday may 11th! He had information about a loan that i had taken out 4 years ago and had the last 4 of my social and my mailing address. I just called them and asked them for a mailing address and every question i asked he had me repeat. (prolly so he could think of an answer?) I had already given them my credit card info but called today to have it changed and they did take out 100 dollars :( He would not provide me with any info but kept asking a case# i told him you want all my info and my card info yet you cant give me your address??? Ugh i hope someone catches these frauds. Does anyone know how they have someon call from your are code?

This people refuse to inform you of any information regarding their company due to security purposes..... Hello, if you were a legit company you would provide a mailing address so a person could send you a payment if you wanted your $$$$, obviously you ain't legit!!!   My lawyer will be calling you soon and we will start harassing you with phone calls... Hellooooooooooooooo  I will pay any debt that I actually owe, but if you aren't going to help me understand what something is you aint' getting a nickel... and watch what and who you threaten people... you may just not like the end result!!!

they call back again today and said did i call the number  18883234724.. and ask did i call them back i told him no he said i will serve you your papers in a hour.. guess what never should up.. so i know this is a scam! i did report this to the ftc  both numbres.. i told them that i would check my local police dept to find if i had criminal file against me which i dont so he hasnt contacted me back today SCAMMER!!!!!

my brother was called and dective nicole mason was looking for me to serve papers on a bad check charge,,I called back and asked for her I was told that person didnt work there.she called again and
told my brother all about this matter I called them asked  for a address and would nt give me the address.I asked for them to stop calling my brother and they did not do that..I am on ssadi

Has any one met with these people to see what documents were given?  or to see if they even showed up to meet with you?

These all appear to be scammers; they are required by law to provide you a Debt Validation Letter.  If not, you don't have to talk to them.

A cluster of debt collectors in California operating in an identical manner were busted by the FTC in October 2011:

I NOTICE THAT THESE PHONE CALLS ALL HAPPEN EITHER THURS OR FRI I GOT THE CALL MAY 11 FRI AFTERNOON.. HE SAID I IN THE AREA I CAN DROP THE DOCUMENTS AT YOUR WORK PLACE REALLY? THEN HE SAID I WILL GIVE YOU A CHANCE TO CALL THAT  NUMBER 18883234724 TO UPDATE MY PERSONAL INFROMATION

yes just receive a phone call from a number 734 931-0081 call my job and said i need to speak to a manager and told my manger that they need to serve me papers and how would he go about doing it.. i took the call and ask who r you he said there was charges file against you.. he gave me this number to update my personal information  1888 323 4724.. SCAM!!!! SO I TOLD MY BOSS TO TELL THEM I DONT WORK THERE ANYMORE IF THEY CALL AGAIN I DID REPORT BOTH NUMBERS

The call came to my place of employment, they asked for my boss and they told my boss I needed to be served with papers. My boss game me the number and stated they sounded like it was important. I called and they would not give me information unless I provided my social security number, name, address and other information. I refused and hung up, they called my job again the next day. Needless to say I could loose my job due to all these calls I am receiving, I need my job and do not need someone calling and demanding to speak to me. They do not want to provide any information to me unless I give out my personal information.

James Davis called from cell phone 318-202-9334 claims work for Process Solution to have been hired by company named Huntington to locate me to serve me with court documents I asked for an business telephone # would not give me one or an address.Dwight Stone and John Wilson from Huntington claiming to have been hired by a pay day loan company wanted to collect imediate payment today. BOGUS never heard of or obtained a loan from this company or any other pay day loan. BEWARE OF ANY COMPANY THAT WILL NOT PROVIDE A MAILING ADDRESS WHEN ASKED, I asked for this several times and was told "that they were not allowed for security purposes". I imediatley called FTC and have filed a complaint. I also requested a new credit report and placed a fraud alert on name and social, this company had the last 4 of my social, then again who doesnt these days.
