Who called from 7813399997

Same as everyone else, picked up the phone, no one on the other end.

I keep getting calls from this number, when I pick up no one is ever there !

I AM SO ANGRY WITH ALL THESE CALLS. I AM DISABLED AND HAVE DIFFICULTY TRYING TO ANSWER THE PHONE

Inept telemarketer? Acts like their shocked if someone picks up. If they're not even going to try to give their sales pitch, why bother calling?

There is back ground noise but no one answers. Calls 2-3 times a week.
