Terrible Internet while my bill goes up over 70%

I have been a customer for over 5 years and my internet started cutting out regularly about 6 months ago. After 10+ attempts to get support, I finally was told the issues were because the router I had was old and did not work with my internet plan. Crazy it took me months and countless days and hours wasted to be told that... Then was told I would be sent a new one. That did not happen, so I contacted support several more times trying to get support. Finally, after nearly six months 15+ attempts that took hours each to get support, I received a new router. But my plan then went to $144 per month just for internet services. Was told I could switch my plan and save, but that was a lie too. Spent many more hours trying to chase that out, but every plan offered came with and IPad or cell service I did not want and would lead to these issues again once the 12 months contract was done. Not to mention the cheapest was still $120 per month. Compared to Ziply that is almost double their cost for the same speeds. Also speaking with friends who are Xfinity customers, and they are getting the same speeds for over $40 less per month than I was offered. Not mention my internet is so bad it cut out while on these support chats three times today forcing me to start over. I was on the chat at 9am this morning and just gave up after over 5 hours of trying to work this out. This is by far the worst service and support I have ever dealt with, and I have no idea how to make things right without wasting more of my time and money.

If anyone has a direct line to reach someone at Xfinity that would actually care to help, please respond with that.
