This is why everyone recommend 2FA. if someone has changed your account email it means he has now all access tou your funds and details. very rare to recover but you can still talk to support.

are you sure replying in the correct thread?
OP is talking about his bitcointalk getting hacked, not about web wallet or exchange account
