Unable to Cancel Internet Because I Cannot Use Voice Calls

I need to cancel my Xfinity home internet service because I have decided to switch to another provider.

I originally contacted Xfinity through live chat because I wanted to see if there was a retention offer of $40/month or less. I was told that the $40/month offer I was seeing was an introductory offer and was not available on my existing account.

I then requested to cancel my service. The chat agent told me that cancellation requires verbal consent and instructed me to call 1-800-934-6489 or visit an Xfinity store.

I have already explained that I cannot use voice calls. I specifically requested a text-based alternative or escalation to Accessibility Support, but I was ultimately told that I must visit a store.

I am asking an Xfinity representative here to please assist me with cancelling my home internet service through text-based communication.

Please also confirm:

1. The effective cancellation date.
2. That there will be no early termination or cancellation fee.
3. That I will not be charged for service after the cancellation date.
4. Whether any equipment needs to be returned and how I should return it.

I have screenshots of my previous Xfinity chat showing the entire conversation and can provide them if needed.

Please do not instruct me to call by phone. I need a text-based solution.
