Q: how do i e-mail the suport centre

If this is an iTunes matter, try this page ...

https://www.apple.com/emea/support/itunes/contact.html

What account?

In any case, you need to change your passwords, contact your banks and/or credit card issuers (if that info was in your account) to report possible fraud. Depending on which account, you may want to abandon the current one and establish a new one with a very difficult password, such as F8&b65eqm$l#j@.

It is very unlikely that your Apple ID account has been hacked. If you are concerned about the security of your Apple ID, contact Apple Support > https://getsupport.apple.com/ - choose the Apple ID path > answer with "Other" & "Topic not listed" > choose your method of communication
