I have received numerous collection letters in the past year. The letters indicate that I owed XXXX XXXX of California that they turned over to a debt collection service. I have contacted XXXX XXXX of California several times and have been told that my record is clear and there was nothing turned over to a debt collection agency. 

I have tried calling the number on the letter ( XXXX ) XXXX and have never been able to speak to anyone as it simply rings and no one answers. 

The letters come from several different addresses and the format of the letter often differs. It is almost like the communication is being cycled through different processes to make it appear it is being escalated. I have even received a letter that had an envelope which was blank including no return address and asked in the letter to write in the return address shown on the letter. 

I am convinced this is a scam
