Delware Solution Payday loan scam! Nationwide

Delware Solutions has been calling me about a payday loan from Fast Cash that I never had.  The information that they have on me is really outdated and they are using information that I may have used on the web. When I ask them to send me something in writing to autenticate their claims, they tell me that they do not need to send me anything.  Which is against the federal collection laws.  They are nasty, will not let you speak, and are threating.  They can threaten all they want.  I can prove this claim to be false.
