In XX/XX/XXXX i received a phone call from a debt collector claiming to represent an overdue XXXX account. I did not recall being a XXXX member and was suspicious.After checking the collectors name online multiple results came up calling the company a scam particularly claiming past due XXXX accounts. When the collectors called me again i called them out on the scam and the warnings on the web. i did not hear from them again until XX/XX/XXXX when another collection agency called me under a different name but with the same past due XXXX account. unlike in XX/XX/XXXX i demanded some form of paperwork proving any such deal between myself and XXXX.no such paperwork could be produced but they did send me a bill wich i have kept on file. They identify themselves as Diversified Consultants , Inc . ( D.C.I. ). I checked them online again and more warnings came up as results on XXXX.
