Hey @ANDRE23, sorry to hear about this.
In such cases, I'd recommend reaching out to our support team directly for further assistance through this form.
Just make sure to use an incognito window without being logged into any Dropbox account and fill in all the relevant information.
Once you do this and get a ticket ID from our system in your email, you can share it with us here so that we can look it up as well.
I hope this helps!
