Who called from 2176894344

two days of calls from this number. They are using  Voice over internet protocol to prevent us from learning who is calling. Of course no voive message was left.

I want them to stop calling!

They call on behalf of vehicle warranty companies offering additional extended warranties.

They were from a vehicle servicing department experiencing technical difficulties so they said they would call back.

Called... local number, so I answered... silence... I didn't return the call.
