You can easily change your address and telephone number yourself under "Account" > "Personal data", as long as you still have access to the current registered phone number. If you don't, please contact the Support Team via Chat.
As the email is sensitive data, this information can only be changed in direct contact with the Support Team. The best way to do so in this case, is via the in-app chat (i.e. start the chat from within the app). Then we can take it from there.
