Confirmation of internet cancelation

I have requested to cancel my Xfinity internet service multiple times and have received inconsistent information regarding the cancellation process.

During my first request, I was told that I would receive a cancellation confirmation email within 24 hours. When I contacted Xfinity a second time, I was told that I would receive an email within 10 minutes. However, I have yet to receive any confirmation email. The only information I was provided was a verbal confirmation number, which I have no way of verifying.

Additionally, I was informed that I would be receiving a refund after canceling my service. Initially, my next bill estimate reflected a credit of -$30.71, which appeared to confirm the refund. However, when I checked my account the following day, that credit had disappeared, and my estimated bill was showing $0 instead.

This entire process has been frustrating, especially considering that I have contacted Xfinity multiple times to complete a simple cancellation request.

I am requesting written confirmation that my internet service has been successfully canceled, including the effective cancellation date. I would also like clarification regarding the $30.71 refund that was previously reflected on my account and confirmation of whether I will still receive it.

I should not have to repeatedly contact customer support just to verify that my cancellation was processed correctly. I would appreciate a clear response and resolution to these concerns.
