Who called from 6462573472

Had calls about a back brace last year different number just another BS scam scum bag call just another blocked number.

Some kind of robo scam pitch for a medical back brace they claim I ordered.  No thanks,. I get this scam every couple of weeks from different numbers.

Won't say anything

This is a new one.  Rang four times and disconnected when the answering machine picked up.

Called, left no message. 2 minutes later, receive another call, caller ID says it is our number calling ourselves??? WTF?
