Intermittent Internet Service for MONTHS

I have had Comcast/Xfinity Internet service for several years. It was good in the past but over the last 5 or 6 months, my service has been HORRIBLE! It goes out several times EVERY SINGLE DAY! I have had 4 techs out to my home and none of them have been able to fix the issue. The last 2 techs stated that the end cap at the end of my building is a complete mess and most probably, a new end cap is in order. Yet none of them escalated the issue. I have called Xfinity more times than I can count and have wasted more hours on the phone with agents than I do at work. If you look at my account, you will see that the agent says they are having someone come to look at the outside issue but when I call back later, there is no evidence of a ticket at all. AT&T laid new fiber optic cable in my neighborhood and I am certain most of my community is or had switched over. I will probably be switching too because I'm tired paying for intermittent service at best and really tired of NO ONE LISTENING TO ME. If I was still working from home, I would have switched already. I'm tired of all my TV shows being interrupted. It.would be one thing if it was a one-off but it has been going on for MONTHS!! That is simply unacceptable and continuous apologies dont cut it. Xfinity has definitely proven itself unreliable and untrustworthy with no true effort made.to solve this customer's issue. If you.had intermittent service of any kind at your home for months, you would be angry too.
