I just got a call from that number, but seeing that it was a phone number I'm not familiar with, I didn't answer. Anyway, if someone calls and the phone number they call from is not familiar to you, you don't have to answer the call.
I got a call 9:15 AM Pacific Time. Same thing about lowering my interest rate. I didn't answer but a message was left. Scam for sure... we need to publicly humiliate those who run these scams. They can be found. I blocked, but they'll get a new number.
received a call on my cell this morning (12-4-15) from this number also -- did not answer as I didn't know who it was. Appears from the other comments that it is a scam or telemarketer of some type.
