SLOW service, NOT HELPFUL staff, NEVER accessible

I have been distraught with Xfinity for the past couple of months. My internet bill was over $200 because I was on an outdated plan. I changed my plan in July to the unlimited plan because the agent who first assisted me promised me the best service ever and that I would be given an xFi pod. My internet is still slow, and it was a false promise.

My frustration peaked when I was charged over $200 in both July and August for supposedly 'going over my data.' This is perplexing, given that I was under the impression that I was on an unlimited plan. When I inquired about the $ 115 charge on my July bill, the agent was unable to provide a satisfactory explanation. Furthermore, I was informed that I wouldn't receive the xFi pod until 14 days later, a detail that was not communicated to me by the first agent and was never fulfilled by the second agent!

I have been in contact with Xfinity multiple times about the issue and I am still waiting for guidance. I called two days ago and was promised that I would receive an email with my xFi pod information, but I did not receive anything. Today, when I reached out to an agent, she told me that I needed to go to the physical store to get the xFi pod. Why couldn't any of the staff tell me that a month ago?! 

I didn't even know that if I decided to cut my internet plan, my mobile line would be charged $25 per line in addition to my original bill. I have no issue paying the bills necessary, but I think it is very crook of Xfinity not to take care of their customer and, more so, to swindle them into paying more for a system that doesn't work. I have been a customer for over ten years, and I have never been as fed up with Xfinity as I have been in the last five months.
