Who called from 4802884567

Random call, no message. Ive received a raft of nuisance calls lately, so suspect this is scammer.

Just called me and left no message. Tried calling back from GV number and received a recording that number you have dialed is not in service.

Listened to message. Robot call stating that they need to speak to you about lowering credit card rate. Press 1 to speak to representative. Hung up. I have one credit card and I am suse they would contact me if needed. Another number added to my blocked list.

My cell phone automatic reply 'Coitus Interuptus; try again later'. Bounced back as not a valid telephone number!  So guess what I say to them?  Anyone wish to reply out there?

called.  left no message.  tried call back with no luck.
