Just a suggestion, call the number back and see who answers.

Called. Rang once. Hung up

Got this call about 10 minutes ago. Never leave a message and I never answer them.

Some how my PREPAID phone that I just got was given out from Tracphone/sold off and debt collectors calling most likely.

Don't answer them.

Unwanted call! Do not know who this was... adding to block list!

Rec'd call from this number... we do not answer numbers we do not recognize. I did call back the number, msg did NOT identify the number, just said to leave a msg after the tone and a repersentative will call me back.  Obviously I did not leave a msg.
