how to delete closed account still showing active

@XfinityDilary​ Unfortunately that doesn't work....everything I try says "can't make that change right now we need to verify your contact information".  When I click on the link provided it will not let any changes be made.

My default account is the one I closed a year ago.  My current account shows the correct email and phone number, so not sure why the verify issue.

but summary, the system will not let any changes be made without the verification process; however, that can not be done for some reason.

any attempted alterations to my account result in the same "can't make this change right now we need to verify your contact information ".

Then when I go to the link provided on that page, again "can't make this change".....

The system will let me delete payment methods (credit cards on file); however, the default card can not be deleted nor can I add credit cards.

@user_f04y0k are you receiving a specific error when trying to unlink the account

The system will let me switch between my two accounts.  When I attempt changes to either of the two accounts I get the "can't make that change right now, etc".  One of the other error messages says "There isn't an Xfinity service associated with this ID". 

The other thing I noticed that when I get the "can't make change right now" the internet  page shows NO CONTACT
