Robo caller - i'm on the Do not call registry. I put in a FTC complaint (located at the do not call.gov site) I'd suggest everyone else do the same.

Called my cell phone.  Left no message.  Added this number to my spam list, however doubtful they'll ever use the ssme number agsin.

My call was about my Non existent credit card debt

I got called by this number claiming that nothing was wrong with my accounts, but they were just offering a better APR rate. I actually decided to have some fun and grill the caller about who they are. 1st I asked for the name of the company and what they have to do with my accounts, he told me they manage all balances for visa and mastercard accounts, and some more garbage along those lines. Then I asked for their website, so he asked me why I needed it, and I told him I`m just trying to figure out who they are. CLICK..... he hung up the phone. Definitely scammers. Beware.
