Just another telascammer. Fake Google or what ever. Blocked now till the next new number.

They do not honor the request to be placed on their do not call list. Google listings will also usually just call from a different number

This number keeps calling and hanging up on my office phone for the business I work for. I have asked to be put on the do not call and have registered the number on the federal do not call registry. What else can I do to stop this spam??
