Stop Robo Call - Nuisance Call Reporting

I see that this topic has been raised by many others before me, but still appears to fall on deaf ears.  Cox MUST do something to assist with stopping these annoying, intrusive robo calls. 

I have taken on a campaign of filing an FTC Complaint for every call that comes in with a phone number - since I have been on the DO NOT CALL registry for years.  So sad that this doesn't actually work like it should nor does the FTC apparently do anything about repeat offenders.  It doesn't help matters that phone companies allow phone number spoofing - so you never quite know where the call is originating. 

Cox, you have a responsibility to your customers to do something about this.  Other phone systems have systems in place that help to weed out these calls.  We pay exorbitant rates but get very little in return. 

Your response, other than a canned response, would be greatly appreciated.
