Who called from 3132184386

When I answered the call, a recording said, "I'm sorry. That is not a valid extension. Please try again."

Ditto

My recording said this is final notice,  push 1 for operator now

I spoke with a (non speaking english at least VERY hard to understand.
He said he was going to give me a lower interest rate on my credit cards.
He ask for expiration and then a card number.  I told him I looked them up
on line as I was speaking with him and as soon as I said that he hung up on me..

I've been getting these calls for quite some time.  when I called them back I got a recording saying it wasn't a working #.  My caller ID said it's from Detroit, MI.  So frustrating.
