Who called from 3343949901

this call showed up on my caller I.D. and when I call back no ring tone then weird noise, hanging up and redialing gets you a bust signal..........

A man named 'Marvin' and a woman call and say they're from AT&T and want a credit card to pay our bill.  Our bill is paid and not even due until April 6th!  When you call this number back, nobody answers.

Scam?  I think so.

repeated calls with no message left

same here - called twice in one night, no message

17 calls in one day. no message and when i tried to call back. get busy or answer and hang-up.
