If you had an exwife like mine, she would transfer your service to another address or tell them that you were moving so shut it off on Friday afternoon if it was possible on the site. She used to get mad at someone and turn all their utilites off. Sending flowers and charging it to your account was also another one of her things. This was years ago before the internet and major credit cards while living in a town where anything could be done over the phone.
I thank God for passwords even though they can be a real PIA to remember.
