Called 3 times today on my former landline. Did not answer and no message left. Blocked via Google Voice.

I received this call three times today.

480-548-6287 called, but left no message.  Reverse number look-up indicated number is not valid.  any information on the source of this number and purpose of the calls.

Why do these pests keep calling, you block the numbers and they just come back on another phone number. I think they sell our number as leads to telemarketers and they just hate to give up if it is a live working number... If you get on the no telemarket list, you block them and they still keep calling, then these are very sick desperate people and no one should ever pickup a phone when you see these numbers. Thank the lord for called ID....
