CapOne gets an A+ for having all the information needed to cancel a deceased loved ones credit/bank accounts. Ask ENO and they give you a link with a number to call, call the number and you only have to push one button. They tell you all the info you need to have; account number or social, date of birth, date of death. Super helpful, very kind.

AT&T-FAIL. You need to search high and low to find the number to call, then you have to have the 3 digit code on the account, good luck if they have....

..paperless billing and online bill pay.

Customer service was EH. Then it was thank you for using AT&T. and while I was on hold, don't get me started on the getting through the bot, they tried to upsell me.

I may not even cancel my grandfathers account, and just let it go to collections. Go ahead and sue his ghost.
