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.

Best coverage

on May 19, 2021

I travel often and I definitely travel around upstate New York and everywhere I go AT&T is faster and even seems to have more coverage than the others, so I am not sure who is doing the tests, but everywhere I have been, AT&T seems to outperform (also I don’t like AT&T as a company, so trust my honest review here).

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.

Good customer service

on June 28, 2021

I called cox about our internet bill going up from one month to the next. The first time I called I was talking to a customer service representative and we got disconnected. I called a second time and had a longer wait time to talk to a customer service rep. This time, the rep was very helpful. He explained our bill and helped us get another discount, and explained how the discount works. I appreciate his customer service skills and how helpful he was. He was even able to get my name on the account, which helps since I call about our Cox bill even though my husband signed up for internet. Thank you for your wonderful customer service skills. Our automated world makes customer service less user-friendly and makes companies seem less caring, but once getting a hold of the company it was nice to receive good customer service. I gave 4 stars instead of 5 because of the long wait time and being disconnected the first time. I give 5 stars for wonderful customer service.
