Who called from 4804367912

Called 3 times in one day.

i have been getting calls from this number several times a day for the past couple weeks.  When I try and call the number I am immediately put on hold and the line is never picked up.

The number calls and hangs up 8 seconds after I answer. No clue who is calling or why. I am called by the number every 2-3 hours, from noon to 9pm
