Celtic Heroes

Hi id like to know how i can change my email because it keeps saying error and i believe everyone is having the same problem as me. One of my accounts doesn't have an email and when i try to put one it wont let me. Is there a different way to do it? like ive tried contacting support in game and they didnt reply back to me and it been 2 weeks now.

Would you be able to provide me with your character name and world and I can check if there is an email linked to the account.

Thanks
