Verification phone number with a wrong digit

Hi. I recently started service with xfinity after some time. I seem to be stuck in a verification catch-22 and could use some help from an official employee. I can access my account, pay my bill, check information, etc., with no problem, but in my account information, there is a request to verify the account via text message. In my account ID information I can see the right phone number, but the phone number associated with the verification of the account has a digit wrong (ending in 5 instead of 8), so I cannot receive the text to verify the account. When I try to change that phone number, it does not let me do it because I have to pass the verification first (and the verification is associated to the number with the wrong digit!). I am concerned I will not be able to do anything with my account because of this. Can an employee please help me reset or update the security phone number to the one already on my profile ID (the phone number ending in 8)?

Thanks!
