Who called from 6123545943

It was comacast.  They needed to upgrade my modem as it was out of date. No additional charges they just don't support the old one.

3 calls today from this number. I did not answer. If it is Comcast, it is not available in my area.

This is K-Designers. The man started in on his spiel, and I cut him off saying I was not interested and to remove me from his call list. They have been calling me for years.  They also call from these numbers:
855-695-4284
777-777-7777 (as if that were a real number)!

I will see if they comply, and if not, I will file a complaint with the FCC.

I didn't answer.  No message left.

Have been calling twice daily. No message left.
