Trying to cancel mobile services

I called and spoke to an Xfinity mobile Agent on 7/24/25 requesting to cancel the mobile services only and close the mobile account. The only thing the Agent did was give me a bill credit because I had not yet received the sim cards. I also chatted with at least 5 Agents on 7/25/25 requesting to cancel services immediately, to have the phones on the account be removed since they were never activated, to remove the automatic payment method, and to close the account. I was assured by each that this would be done and I would receive an email confirmation. The only thing that has been done to the account was deactivating the phones. The payment method is still on the account and the account is still open, just marked as "deactivated." Under your mobile customer agreement, I have the right to remove the automatic payment method but the account does not give me that choice.  I am still waiting for the email confirming the mobile service cancellation that each of the 5 agents insisted would be sent and as of 7/28/25 I still have received no email confirmation of the cancellation.
