Hostonce - Cancelling

I wanted to get out of the contract with them for a long time ago. I think it was october 2006. I asked them I wanted to get out of the contract, but they told me I had to stay with them until october 2007, since they had already extended the contract ( without asking me. ) I contacted them October 2007, and then they said I only can get out the contract after March, since (again) the contract was extended. Now, I contacted them to get out the contract, I posted the message, at their helpdesk and sent email to the billing department. No reply for a week.

I just need to switch the host. My newhost is helping me, but unless they relese my domain, I can't switch. and they don't give me the authorization code. Hostonce is terrible host.
