Who called from 5203996721

receiving calls from this number and no one is on the line. I beleive it is some telemarketing source but these are unwatned calls.

Same as other notes, keeps calling my cell no answer or message.  This should be grounds for a legal harassment charge.

Call (800) 761-6674 and speak to a representative.  It is a casino services company or something along those lines.  Apparently they have been having problems with their phone system.  I just got myself taken off the list.

I get few calls a day from this number and when I pick up they hang up.

this number calls my cell 5 times a day or more.. very annoying called back, verizon cannot complete the call. no messages
