I have used A T & T for the past several years and the service has been great.
There was an issue with the internet set up as there was no AT&T fiber box in the new apartment unit. We called customer service and it took three days to resolve. The technician missed our first appointment to fix the issue but came the next day after we called again. It took us several hours on the phone with customer service to get to the bottom of the problem but they did take care of the issue and gave me a $10 gift card for missing the first appointment. Overall, I am happy with their service.
My connection is lost at least a couple times a week whether watching live tv or DVR
