Who called from 3143966505

I get 2-3 calls per day from this number but no one is EVER there. If I call back, I get an error message that the call cannot go through. I really would like this to stop.

We have been getting calls from this number daily for the past week or so, no one online when we pick up. Can not call number back for some reason

They call 1-3 times a day sometimes there is someone on the other end - most of the time there is not. When there is they ask to speak to the owner, then they hang up. They refuse to listen to "removing me from your list" AWFUL people. DO NOT ANSWER! BLOCK NUMBER IF POSSIBLE!

Same here, answer the phone and they just hang up?  Any ideas?

Caller ID says "Support Int."   No one every there. Does not sound like any one hangs up. 4-6 Calls a day.
