Who called from 6465880050

Did not recognize the number, didn't answer.  Hung up on answering machine.

telemarketers....

Call when away.  Looked up number on this website and blocked.   Decided to call them back and before doing so changed setting so that my number would not be visible.  A recording said if you want your number removed from this list press 1. Of course in such a case you do not press anything - you just hang up.

Some dimwit called claiming to be from senior services.

Called our office, nobody was on the other line when I answered. The call was blank and wasn't disconnected for at least 30 seconds.
