I have spoken with them and they claim there is some sort of claim against me.  But won't divulge any information.  He only provides me some 855-410-9599 number that I can't verify, and I refuse to call it unaware of whom it is.  He claims its a firm called Nationwide.

I had the same person contact me. Some claim and no other information.

This place called my work and told them they were going to serve me but only had my work address and wanted the office to give them my home address which they of course refused to do... made some sort of claim that they did not want to affect my employment (while divulging such specific and personal information).  There would never be a creditor who would only have my work address and not my home address.. so this seems very suspicious to me.. called the number and yes Nationwide is what it says-- hung up and did not wait for the next agent.
