When a call comes in to my home phone and caller ID reads INVALID NUMBER in place of a name the chances of me answering that call is ZERO! Caller ID shows this number called at 6:15 PM on 2/27/2016. Caller left no message when I did not answer. Reverse Whitepages shows no listing and invalid number yet Frontier allowed this call to be completed. WHY!

Just got yet another call from this # which I had previously blocked--HaHaHa!!!

This number called my home phone again on 3/9/2017 at 7:30 PM again with INVALID NUMBER shown on ID in place of name. Still no listing on Reverse Whitepages. Do they really think anyone would answer a call when ID reads INVALID NUMBER? I did not and caller left no message when machine did.

Called at 3:51 PM. No company name.  Only the phone number in caller ID.  No message.  Blocked

Invalid number BLOCKED
