The account was deactivated when my credit card expired. I corrected that problem immediately, then contacted the hosting company. Their response was to resubmit payment and my accounts would be reactivated, which I did.
After about two days, only one of my three accounts was reactivated. Since then, I have sent numerous emails to them with no response.
So, to answer your question, no I haven't been able to retrieve my files. As to whether the accounts are just deactivated or terminated, I have no idea as I have received no response from them.
