account hacked

My account was hacked and the thief changed my account information ... I received an email saying that my account information was changed and if I did not authorize the exchange I could get in touch with the Z8Games ... I opened a ticket but it's been 24 hours and so far no one has answered me!

I have the login id, secret answer and email saying that my information was exchanged ...

Please help me, thanks!
