Who called from 3210000009

called me today at 11:30. no mess left....

They called saying they were from card services to lower my interest rate on my Visa. They told me that I owed way more than I do and when I started questioning them they hung up. I tried calling back and the number was not a working number. Now I am afraid that it was some sort of scam and that I was somehow hacked. I asked them what card and they said Bank of America, Sears, Chase, and some others.
I think this is really weird. Wishing I wouldn't have answered now!

I got called too, as did my husbands phone.  We didn't answer.  The number looked like a count down.

Received call,  Did not answer.  Obvious spam.

Funny.  That area code goes to part of the East coast of Florida where NASA launches rockets.
