I'm getting back to my old question. I got my account activated and changed it to monthly billing, domain was renewed for free then. Soon after I decided I won't be using hosting, so I just ignored invoices, which was probably stupid. Now I "woke up" that it's better to make sure I won't lose the domain. I cannot do much in the control panel with suspended account.
I contacted support and they said I need to pay unpaid invoices to retain the domain, they can disable hosting only after the account has been re-activated.
Is this really the case? I think I read here earlier that in this case one needs to pay $9.95 domain registration for the ongoing year to compensate free domain. I would have no problem with this, it's only fair. But it seems a bit unfair to pay for service you couldn't use with suspended account.
Again, I know I could have handled this better on my side, no need to point it out for me
