Xfinity Mobile Billing Dispute

I was an Xfinity Mobile customer up until July 11, 2025 at which time I cancelled my service and went with another provider. I received and still have the email sent to me by Xfinity Mobile dated July 14, 2025 confirming the cancellation of my service. 

I was then billed (to my CC via Autopay) by Xfinity Mobile on August 1, 2025 for June 12 - July 11 service. (Invoice Number 283337666 for $26.25). I filed a dispute for this charge through my bank because prior to this I was billed in advance. 

I was then billed AGAIN by Xfinity Mobile on September 1, 2025 for July 12 - August 11 service. (Invoice Number 291003405 for $53.94) This bill was for the amount which I had disputed ($26.25) but also included:

1) a "late payment fee" of $5.00,

2) a $20.00 charge for "Shared Data"  

3) a "Home's Services" charge of $1.61

4) "911 Fee" of $1.00

Even though I think the $26.25 I was billed is bogus, I'm willing to eat that. What I'm NOT willing to accept is the additional amounts included on Invoice Number 291003405. (A difference of $27.69)

I have already gone through the bother of trying to work with your "Direct Messaging" that turned into nothing more than 2 weeks of wasted time ... Xfinity: "I've created a ticket for this issue you will be contacted by a representative",  2 days later with no contact ??  Xfinity: "Ticket says they tried to call you but you didn't answer" ... Me: "I have no missed phone calls and I've had my phone by my side 100% of the time"   .... Xfinity: "Oh well then they will try again to call you" ..... Another 2 days with no call ??.  Xfinity: "Oh they say they sent you an email"   .. Me: "I've not received any email from Xfinity, can you resend?"    Xfinity: "No sorry I can't resend"  Me: "What ???????"   Xfinity: "We now consider this issue closed"  YES I HAVE SCREEN SHOTS OF EVERY BIT OF THIS COMMUNICATION NIGHTMARE.

I expect to see a credit issued to my CC in the amount of $27.69. You have all the information required so I fail to understand the need for any phone calls or emails. I've been a customer (Diamond) for 25+ years. Just do what's right so I don't have to escalate this further.

Thank You
