called it back and a recording said if you wanted to put this number on "do not call list" press 1, so I did and hung up..

Received call from 620-979-9014 (on 07/21/2015) 10:45am, appears to be offering lower interest rate on many and all credit cards. Upon further conversations with them, I FIRMLY BELIEVE IT CLEARLY IS A FISHING SCAM OR FAKE CALL CENTER TRYING TO GET YOUR PERSONAL CREDIT CARD INFO. (I had given these people fake info of my own to purposely waste their time and I managed to catch them in lies or not consistent at all in what they had to say). To say the least, very, very unprofessional was the 1st red flag. I double checked with fraud department of Bank of America for confirmation of this scam. PLEASE BE VERY AWARE!!!!! YOU HAVE BEEN WARNED!!!! (W. From Ore.)

Called my cellphone. Didn't leave a message. CallerId said "Treece, KS"

google treece  KS. It's a literal 'ghost town'
Those idiots aren't even smart enough to find a town that actually has living people in it

after talking with the guy for about 5-6 minutes (knowing it was a scam), I played along with his questions. Eventually, when he figured it out, he got mad and yelled at me saying that I was wasting his time. LOL! Well. Boo. Hoo.
