Unknown number did not answer. Robo left a message that there was something to do with my credit card but it wasn't urgent. Then went on to say this offer expires today. Final notice. Wants to reduce my rate. This caller never identified themselves either on CID or on the recording. My 1 and only credit card ALWAYS announces themselves by name AND caller ID. I blocked this number as a SCAM. If you ever think this kind of call is legit, take the time to get your actual card or billing and call the number listed there. NEVER EVER give info to this kind of caller and NEVER EVER call them back on the possibly fake number they gave you. LOOK at your card or bill for contact info.
