Called our business. CID only said VOIP CALLER. Nobody was on the line.

At least six calls to our business in two days from this number. NOBODY is EVER on the line!!! I called back repeatedly until I finally got through. They are some company trying to sell electric services. I politely asked them to please remove us from their sales calls. I am not changing service providers to some fly by night POS company. I could not even understand what name he was saying for the company. His phone line was doing some weird clicking noises.
