Garbage customer service

Honestly I keep getting let down but the customer service. My internet bill went up from $55 to $104 in a month due to some 5 year promotion ending, I called and asked if there was anyway they could lower my bill, the lady said she lowered it to $67, fine. Next bill rolls around and I got charged $104. I was fed up at this point and called to cancel my services. Took forever just to get it canceled then noticed it wasn’t reflected as canceled on my app so I called back to confirm my services were canceled. They confirmed it was canceled… well to my surprise, I got charged $104 again the following month for services I wasn’t even using because I was told MULTIPLE times it was canceled. Now I’m trying to get ahold of billing to get the refund and it’s impossible to get anything done without spending hours on the phone. I would never ever recommend Xfinity to anyone.
