Who called from 8645512636

This number calls my phone throughout the day & no one is on the other end. When I call back, the phone does not ring or anything.

I'm also getting calls from this number.  Dead air and it doesn't ring if you call back.  It's most likely a telemarketing robocall to determine when you'll pick up so they can sell the info and your number.  Scumbags.

Stop calling me. If you had something I wanted, I would call you.
