Can not reactivate or delete accounts

I have 3 accounts that were blocked due to inactivity (my bad). But as for now it is impossible to reactivate them (always getting an error). Moreover, there is no any option to get rid of those accounts. So they stuck forever and I can't use them.

IMHO there is some bug in accounts management that prevents them to be reactivated.
