Restricted phone caller said i had two hours to call above phone number because im about to get a failure to appear in court. Couldnt give me their name for safety reasons. I called above number and talked to a Michael, said i owe from a hospital from 10/7/2007. Said they tried to serve me, wrong address, wanted my new one, and he has my social security number, he read it to me. I started the address, but stopped for scam reasons, then he proceeded to give me my current location. Said he got it from my credit report, vut earlier said he didnt have it to serve me. They have also called my parents in a different state. I asked for the company name, address, and who they were trying to collect for, that they say is from wpg and wont give me that address, and that i will be served in 3 weeks. I called the said company from the internet, they are a immigration attorney, not a debt collector. Now im worried due to the factthey have my social security number, from who or where im not sure.
