Xfinity service and Customer satisfaction

I’ve had xfinity for 4+ years and have ordered higher internet on their suggestion on a contract and still had to move my office space downstairs to stop dropping. I have had so many service calls I can’t even count how many times I’ve had to call and get someone to fix the  issue after numerous reset, reset, reset, and reset and yet somehow the higher network still acts the same. The constant buffering to watch a movie or dropped service when I’m working. I’m the only one on a computer during the day so I should not drop and sometimes lose the work performed. 

Yes I’m being critical which is not my norm, but you should  provide your services you advertise on TV.
