A version of this happened to me too, but luckily the reason I was trying to login is my account was being shut down because my credit card had expired. I was able to get through to tech support, but their mechanism for unlocking my account was horrible. I still owe them some trivial amount (<$100), but the tech support team said they had no way to bill me for it unless I could log back in. So at least it's biting them both ways.
