Overcharged and Unprofessional Customer Service

Long time customer for years. Finances got rough due to everything going on with our economy and applied to downgrade to a cheaper plan. Got approved. Called in a month in advance to ensure ample time to make the changes. The plan was to transfer downgraded services to new residence. Phone call communications were rough with long wait times but to ensure a smooth transition I dealt with it. Customer service reps made all necessary changes on their end over the phone prior to the move, or atleast that's what they had me believe. After I moved, Xfinity did not stop my previous plan like they said they would. Months later, they abruptly shut off my services even though I made every automated payment on time with receipts to prove. Had to call in to re-explain everything that was supposed to happen before my move again and again. The last person I spoke to on the phone, "a supervisor", was not helpful at all and instead blamed me for being overcharged and not noticing xfinity's mistake sooner. Shady business. Unprofessional. Would not recommend to anyone.
