Credit corp using multiple numbers including this one. They don't respond unless you do, they say you owe money when you owe nothing. Never admit to a thing, question everything ring them back and harass the hell out of them. They'll hang up on you after telling you off. They know what they are doing is illegal. They can only call you 12 times a month if you answer.
