Wanted my credit card info

They kindly let me know I am receiving $5000 loan, I never asked for. I have put this number on my auto reject list. Called 3-4 times a day. When I nicely asked for the supervisor, the "man" started to be rude an vulgar with me.
Once I find out who they are, they will be in great trouble.

They claim to be a (unknown) "Collection Agency" calling to collect a debt for a Shawn Hush. We do not know this person and have followed all the Phone Companies suggested resolutions to getting the calls stopped. The calls keep coming, just today 8/30/14, alone we got 9 nasty calls and said 9 times to 9 callers and "Supervisors" -  we do not know this person, they have the wrong number - Stop calling.
