Hi @Didilacarotte !

Here is solution which I found on Deezer support page :

Whether you've forgotten your email, your password or both you can find your account and reset your password with these steps:

1. Go to our password reset form
2. Enter your email address. If you have multiple email accounts and are unsure which is the one linked to your Deezer account, enter all of your email addresses

   You will receive a password reset email from Deezer

3. Select the link within the email to reset your password

Note: When your password is successfully updated, you will see a message on the screen

Hello thank you for the response but... unfortunately  thar doesn’t resolve  my problem.  The point is that  the email that  I used to create the account  is wrong: it’s existant  but not even mine, so it’s impossible for me to do anything.  Not even cancel the created account by myself. And I paied with my card. It’s 0€ for4 months but after that I’ll have to paie for the account that I can’t use.

Hi @Didilacarotte please get in touch with our Deezer Support Team and provide the wrong email and payment information, and one of our agents will help you to update the email on the account.
Thanks :)
