Techs claiming to submit maintenance tickets

Four techs have came out and said there is a problem with the line going from the ped to the main.  I have repetitively called, chatted and texted COX.  I paid for the extra tech support and still getting no fix.  I have now replaced the standard equipment with top of the line NETGEAR modem and router that I have invested hundreds of additional dollars into. 

Every tech said there is a problem in the ped to the main and told me directly that they will submit a maintenance ticket to have it checked and fixed, yet nothing is being worked on or fixed.   I pay almost 200 dollars a month for internet and tv, but internet will not work and send signals at times that are less than a third of what the plan is that I pay for.

I need a fix and answers of why things are being ignored by this company.  And the worst part of it all is their is no other option for our neighborhood. 

A frustrated and feeling underappreciated customer.
