Who called from 3122793318

Keep calling me every day 2-3 times/day. No voice messages

Calls 3-4 times a day when you call back it is a non working number. Some sort of scam apparently.

Keep getting calls 2-3 times/day from this number, then when I call back no answer.

I'm getting really tired of phone calls from this number,

Keep getting daily calls, sometimes more than once.  I try to call back, but when I do the line picks up but then silence.
