Who called from 6313183050

Called my mobile phone.

called my mobile. i picked up and said hello and heard creepy breathing on the other end. they never said anything back

called, no answer

Called and said i won a a walmart giftcard and was signed up for a sweepstake. most likely scam!

they called my cell. did not leave a message. Didn't pick up since i did not know who, what, where the call was coming from.
