Can't delete websites "Cancelled for Inactivity", meaning I've reached the website limit

I usually use 000webhost for lots of different websites as little jokes with friends, but recently 3 domains were cancelled while 2 remain active. This means I’ve reached the limit of 5 domains and I can’t delete the cancelled ones. I contacted 000webhost with no response. Can a staff member help?

You can not make any new sites using the old panel.
Sign up a new account with a new email and all functions are able.

ugh

Can I change this account’s email?

You cannot change the email on the old panel no sorry.
