Who called from 2136039076

Received call to business. Left no message on machine.

I can't block the call but I can let it ring and ring and ring......unplugged the answering machine.

Called 5 times today, 2 in the morning and 3 in the afternoon. Each time they hung up before I could answer. Glitchy telemarketing robo system? I'm on the national DNC list (of course) and am seriously thinking of getting rid of my land line now, since I don't have this problem with my cell phone.

Rang wireline. Call blocked. No name, but repeating the calling number.

did the same here..not in my area code..
