Horrible service and terrible customer service

I signed up for 60 month internet. First comes it change to 96. No notice nothing. Try use chat I option which is total waste of time.  Seevices cut off and on, discount from devices, go out completely at different times of the day. Then they want to charge me to have tech come out to fix there mess up service.Then I spend hours on phone customer service to get nothing resolve. Just listen horrible excuses. Then to cover up they offer more horrible services at discounted rate. I'm done with xfinity internet services. Only good option they have is go now phones. So far. Please look into improving your customer service and services.
