Fantastic team and great coverage

on September 28, 2019

Absolutely fantastic! Tech came out to help install and, due to the wiring in our apt, it took a while to find the correct outlets. But he was so patient and helpful and kind, really going above and beyond to make sure things got set up so I could have the level of coverage needed to qualify for work from home. Truly amazing guy, I honestly can't speak highly enough of him. He kept trying long after I suspect most would have given up. Huge THANK YOU to AT&T for the coverage at the right price (literally half the price of the competitor in this area), and more importantly for having such an amazing guy on your team. Thank you.

Amazing Customer service

on October 23, 2019

This is how great Cox customer service can be when you let them help you. I made the mistake of letting someone trick me into letting them in my network. Before i knew what was happening they were in everything, they even wiped out my virus program. When i called Cox for help i was connected to Catherine in the Ohio call center, I explained to her what had happened & how worried i was about everything. Right from the start Catherine said it's going to be OK & i can help you take care of this. Then she said asked me to to take a deep breath & try to relax & i'll get started. Catherine was the most caring, understanding & thoughtful person you got hope for & just as smart. She started with the network & cleared every program they had installed. Then she asked me a few questions about my laptop at which time you asked me for permission to access it in order to make sure that no program was left behind which could still allow them access. I said yes & Catherine started going through the files & removed a few more programs they had installed. When she finished she then explained how with my Cox account came a McAfee Virus program which was what i had in my laptop. She then reinstalled McAfee & helped me set up new pass words for everything. When Catherine was done i felt relief for the first time in twelve hours & when she was finished & i thanked her for everything, she said you don't need to thank me it's me job. I said yes it may be your job but you just don't know i great full i am. So to show just how great full i am wanted Cox to know just how much i appreciate everything Catherine did to save me from what could have been my worst night mare. Catherine is the perfect example of outstanding customer service.

COX specialist in Mesa, provided outstanding service on 3-27-2021

on March 27, 2021

It was necessary for me to unplug my COX cable modem, return it to a COX store, receive a new cable modem, take it home and spend time getting it working. Not something I wanted to do on a Saturday. Luckily, I was assisted by a specialist in this transaction. He processed the return of my old cable modem, showed me that my monthly bill would be lower, activated a new cable modem for me, and suggested several ideas that would get my home internet back up quickly. Internet connectivity configuration can be tedious, even on the best of days. Today was different. Using his suggestions, my home internet was working in just five minutes after attaching the power cord and coaxial connection to the modem. No online support chats, no longer support phone calls. Certainly, the easiest reconfiguration one could expect. He probably helps 30 store visitors per day, but just know that one of those visitors greatly appreciates your personal attention and flawless execution of the tasks involved to keep a COX internet customer very satisfied.
