Cannot reset my account after being hacked.

Account was hacked approximately sometime last night. I can not remember the last time I updated my contact information and have exceeded the number of tries to get it back today. Every time I fill out the form with as much information as I can, I get an email saying it was not sufficient enough to restore my account. It may be because I haven't used this account to send very many emails for a few years now, but I have been using it to receive important emails that I no longer have access to.  I have provided as much information as I'll ever recall and still can not get it back even though I'm using the same IP address that I've been accessing it from since January. Please help? (Removed by Moderator)
