Hey @Klopeks, welcome to the Community!
Oh! this sounds pretty bad and honestly I've heard cases like this and normally a restart fix it, but you mentioned that you already tried that and it didn't help. So, in this case I suggest you to get in touch with Fitbit Support directly so they can take a look of your account and choose an alternative option to help you out.
Hope that helps!
