Xfinity sends me a bill after cancelling...

or apparently, even schedule a callback anymore. 

Good luck with trying to get a satisfactory resolution to this. I'm going through the same thing (since July 10). I've once again been billed on September 2 and this bill even has a $20.00 fee for exceeding data allotment!! I've been with Mint Mobile since July 11th!!  I have all of the emails sent to me from Xfinity Mobile confirming my cancellation then an email telling me my service was disconnected "due to non payment". I could go on about all of the emails, copies of chat discussions, direct messaging (xfinitysupport) It's like a never ending nightmare. The result of my "direct message" efforts were to be told that a ticket had been generated and I would have to wait to be contacted by someone at Xfinity Mobile. Well I didn't hear from anyone so I sent email saying so and response was that they tried calling me and I didn't answer. I had no missed calls!!!! They already have all the information required (dates, invoice numbers, emails, chat correspondence etc.) They're just giving me the run around.  I hope you have better luck than I've had.

Hello user_5doj2c! I appreciate you reaching out with your post, and even more appreciate any amount of time you spent with us at Xfinity 👏 The last thing we want is for you to be charged for services you no longer have, so you'e in the right place to get to the bottom of it! 

Please send us a direct chat message with your full name, the name listed on the account (if different), and the full service address associated with your account to “Xfinity Support”. To do so, click on the chat icon located at the top right of this forums page.

I am dealing with the same issue, except I made several attempts at having them pro-rate my bill before the cancellation date. Multiple reps lied to me about the billing team having a ticket to fix my bill and then when I was charged the full months' service, I had to spend additional HOURS talking to several reps about a refund. I am STILL waiting to hear back about when I can expect this refund, despite several agents assuring me I should have it by now.

I am direct messaging with someone in response to my own post in this forum and all they've deigned to give me for information in the past 48 hours is "Upon reviewing the account, you have a credit balance of 63.34. The last bill that was generated on 8/6/25 for the billing cycle of 8/13-9/12 was for 107.05. We prorated the bill and credited the account from 9/12-8/30 in the amount of 47.86. A 15.00 credit was applied to the account, and .48 taxes and government fees were credited, giving you a credit balance of 63.34."

As if I'm not the one who chased down the agents via chat so that they could arrive at that credit amount....

After reviewing this forum, it almost seems like Xfinity purposely overcharges people who cancel, hoping that they don't care enough to ask for a refund and if they do, makes it impossible to get one at all. This company is full of dishonest, fraudulent employees. If you're reading this and have yet to enter into a contract with Xfinity, spare yourselves the exhaustion and financial manipulation and go elsewhere. 

For the record everyone: they viewed my direct message 10 hours ago and did not respond to it.
