Your profile is personal, which means that you may not give out your login to others. Therefore, you also do not have the opportunity to change the email address on the account yourself.
But as long as your profile is not used by anyone else, you can change your email address. Just contact customer service with information about which email address to change and what it should be changed to and they will help you.
You can contact us by email via mail email@example.com or via messenger. Our support is available on weekdays from 9 a.m. to 3 p.m.
