DNS Remove

Whether there is no hope depends on how iFastNet responds and what verification procedures they will ask for. I usually go for domain verification through DNS in such cases. It lets you prove you own the domain name (which means you can decide where that domain should be hosted) without having to prove you own the original account. But my opinion is irrelevant here. Your domain is not in use on InfinityFree and so I do not have the ability to release your domain name.
