email change FAIL

I'm unable to change my email from my old email provider to the new one (gmail).

It doesn't work from old Netatmo app, neither from the new control app, neither from the website.

Also, I changed my password and now says "wrong password" when I try to change the email... And I am able to log to apps and website, so it's a KO from the Netatmo servers...

Finally, not a single email for support, only a form to delete my account... And I need to select a "TOPIC" for "nothing", as no real topic for ACCOUNT SUPPORT...

Uncroyable...
