Change Mail of Acc

Dear fellow players or mods,

I would like to change my Mail of my account but I have no more access to the Mail. The acc is almost 10 years old and do is the Mail and does not exist anymore. I have login, passwort, my birthday (in case I didnt lie when I created the acc), my name, maybe the security answer if I would know the question and I have access to the payment methods I used to recharge zp. I hope that you can help me.

Kind regards,
Tom.
