I also dont think you will be able to get back that account now even if you accept your mistake.Yes you can contact on the mail which has told to you or theymos but you never gonna get reply to that i am sure,so it would be much better to forget about that account and if you realise your mistake,then dont do it with you other account again.
Try mailing again to the id given in red. Unless they respond, they wont write out their mail id. I checked with any option available to suggest. He said the account can not be opened back. Once banned is banned. Better start your business with your new account. We understand this is hard to get back all the contacts lying in that account. Your new account would be a source to start over again.
