Who called from 6319543321

Calls several times a day, just to hang up when answered. Number does not take incoming calls.

CALLS ALL WEEK SOMETIMES 3X A DAY, DOESN'T TAKE CALL BACK

Calls around the same time every day. No one on the line. Anyone know who this number belongs to?

They call about twice per day, every day. No message. Today I answered and they hung up. I tried to call back and call would not go through.

got a call from this number today. I had said hello and it was a male voice who sounded like they asked for someone but I couldn't make out the name, with the call ending with "please." I waited a bit, and decided to call back as I get friend's with new numbers who've called before, but it said it's not an active number, or it doesn't take calls something like that. Idk, I decided to block it.
