Billed after cancelling

Same issue. Changed plans 2 in august to a plan where I was supposed be charged $40/month. They charge me $60 for the past 2 months. I contacted multiple times for a refund and have still received nothing. Costumer service was consistently rude and unhelpful. The last time I spoke with them I was told I would be refunded for the past 2 months I was charged over and I asked them to cancel my subscriptions. Never received any refunds and I was charged again this month although my account shows no subscriptions. On top of that they charged me well over $100 for canceling my subscription when I only had completed my 1 year contract. The new subscription I cancelled after 2 months was because xfinity was not upholding the terms of the contract ($40/mo). I don’t see why I am being charged over $100 for breaking a contract that xfinity never adhered to in the first place. Meanwhile my speeds have never been anywhere near what they said they would be (100mb/sec) and have been below 10 mb/sec every time I have run a test. I’m lucky if I can get 1 device in my house to run on wifi. On top of this the prompts to reach customer service on my app and by phone no longer allow me to reach a customer service representative, so I now have to physically go to a store to request refunds for the now past 3 months I have been wrongfully charged. The worst service I have ever had. DO NOT USE XFINITY!!!! They will squeeze you dry for absolute worst internet service that they can never fix or improve and then charge you even more when you cancel because they are completely incompetent and don’t give a <Edited for guideline violation> about their customers.
