Supercell - my clash royale account

Hi Support Team

As I've contacted to Supercell Support to help me change the email which is tied with my clash Royale account.

They have not helped on this, then I contact to you for helping, could you please help suggestion what I can do on this.

I need to switch email cause my company email will no longer use it, then I gonna move my clash royale account with new email.

that what I got issue now.

Thank you very much
