Who called from 6502389972

Several calls from this number to my work. Nothing is said when I do answer and no message is left when I don't answer.

So for the hell of it I called this number back and an automated message said to press 1 to be added to the do not call list. No indication of the company or purpose behind the call.

Received a call from this number. Said "Hello" and they hung up.

Same as Samantha has reported - an automated message said to press 1 to be added to the do not call list. No indication of the company or purpose behind the call. Sounds like SPAM.
