So apparently to stop robo calls or spam calls, you will need to buy a Call Blocker for 69.00, or a caller shield for 99.00, from of course, Verizon... I recently switched from Cox to Verizon. I never had this many robo calls as I do now. And again, the only way to stop them is to buy equipment from the company that lets the spam calls through. Sounds about right.
I don’t know if you both are referring to verizon home phone services. If so verizon offers a 100 free call blocking service. Or better today per the FCC
