Battle.net account locked with no way in.?

[Brandan]

So I think I managed to lock my account for suspicious activity by accidently using thw wrong password 2 or 3 times.
I followed to guidelines to reset my password, but for security reasons I have to enter my first and second name. I cannot remember if my second name is registered with my account, but I know that my first name is, and I have even checked my old email of when I first registered with Battle.net that my First name was correctly input. But it would not accept it, I tried all possible spellings of my first and second name and it still wouldn't work.
I tried to submit a ticket for help but I have to sign in to do that.
I tried getting help via the Live Chat, but I cannot get into it, every time i input my problem they tell me to send a ticket (which i can't do) or phone them (which I also can't do for a couple of days).

Is there any other way to get in touch with blizzard at Battle.net and get this sorted?
I have tried emailing their support mail, but they don't respond to that now.
