Every so many months XXXX XXXX places an account with a collection agency which is not my bill. I have requested over the years proof of this bill and it always ends up that they can not provide any. In the past I have filed complaints against the collection companies and I think the best action is to get XXXX to stop reassigning this account over and over. 
The company they have assigned it with this time is listed below and they seem at this point to understand after reviewing XXXX XXXX 's info on my account they refereed that something is n't right. 
I have also requested that the collection company send me proof of this debt via phone and email. The contact person at ERC is a XXXX XXXX at XXXXERC, XXXX XXXX XXXX, XXXX, XXXX XXXX
