Who called from 5712988720

Received a call from this number and answered without speaking.  Dead silence on the other end.  After reading all these comments, this caller has been blocked.

Picked up because it looked like my boss' number. Ended up being "Heather" from "Account Services." Definitely a scam.

called about lowering my interest rate. Scammers

ditto.. also added to reject list.

Didn't answer and called back, it's a credit card scam.  Why isn't anyone doing anything about these people?
