I really don’t want to have to sue Xfinity but y’all are pushing it

I’ve seen threads with the same issue I’m having  and it appears to be a serious, persistent issue. I’ve called several times after my internet service was very slow or just flat out didn’t work. I was swindled into upgrading to XFi after the sales person lied and said it would expand my coverage and they never even sent the right box. After months, I finally got the new gateway and found out they upsold me under false pretenses. Even with the new device, on multiple occasions my service just stopped working and I work from home so this is a major disruption. The last time, my service was out for two days and after troubleshooting in the app and over the phone I was told I had no option but to have a technician come out. The technician comes, fixes something outside, NOT IN MY APARTMENT, then leaves. There was never a mention of an additional charge. A few weeks later the service goes out again and I happen to check the app and I was charged $100 for the technician to come out. The audacity!! Now I’ve called multiple times and the call is either mysteriously disconnected or I’m on hold for over an hour with no solution! Completely unacceptable and illegal for Xfinity to continue lying and stealing from customers.
