The Scammiest Company I have EVER Dealt With

When I originally signed up through a 3rd party my internet bill was $10 more than it should have been. I called trying to get that resolved and was promised a call back that never happened. For the next few months I would call xfinity regularly asking for them to lower my bill, and every time I was promised that someone would call back with an offer. Again and again and again, and I never received a call back. After a year of this I decide to cancel my service. This was the first time someone offered me a lower bill, once I was already done with them. I declined and asked them to cancel my service as of 11/7. My move was delayed so I called back later and spoke with someone and asked them to change the cancellation date to 11/14. They agreed to do so and heard me about my complaints. I finally felt heard and was promised a refund due to the horrible customer service I received over the last year. She also told me I would be charged a lower rate than I had been for the extra week. She said the refund will be reflected on my next bill. Imagine my surprise when I get a bill for $111!! There is no refund on there, it is at the higher price, and I don't see anything about the cancellation. Unbelievable. 

I am beyond frustrated and disappointed. I regret going with Xfinity more than anything. I can not believe I was promised a refund and then got a higher bill. At this point I plan on contacting the Better Business Bureau, the State Attorney General, and the FCC. This is ridiculous. It has to be illegal to make so many false promises to someone about money.
