service cancellation and payment

Hi, I need help regarding my recent Xfinity service cancellation and payment.

I made a payment on August 28, but that payment was for service period from September 11 through October 10. However, I decided to cancel my Xfinity service, so I went to an Xfinity store on August 28 and requested cancellation. At the store, I specifically told them that I wanted to use the service only through September 10. Therefore, I believe I should receive a full refund for the August 28 payment that was made for the service period from September 11 through October 10.

I received an email confirming the cancellation, but the confirmation email does not show my last day of service. I also have not received a refund for the unused portion of the payment.

The payment was made directly from my bank account. I read in the Xfinity FAQ that if a payment is made by electronic funds transfer (EFT), Xfinity will send an email requesting those documents.

However, I have not received any email requesting documents or any information about the refund.

Could you please:

1. Confirm the exact last day of my service.
2. Confirm that my service cancellation was processed correctly.
3. Confirm that I am eligible for a full refund for the September 11–October 10 service period.
4. Let me know what I need to do to receive the refund, including whether I need to provide proof that the payment cleared my bank account.

I would appreciate it if you could look into this and provide a clear update on both the cancellation and the refund. Thank you.
