All they would say is that they were ERC (Enhance Resourse Center).  They wouldn't give any info on what they were calling for.  They were just trying to get info from me.  SCAM!!!
I looked them up and it said located in Jacksonville, FL, but the number they called me from is a Buffalo #.  Been getting lots of calls from different Buffalo#'s lately.  SCAM!!!

Buffalo and the surrounding area is the World's #1 area for criminals pretending to be debt collectors.  I suspect that is why they called you, because they want to extort money from you.  Are you sure that is the company name they gave you?  Also, what sort of questions did they want you to answer?
