Can't log in with email, I never get the one time password email

I'm trying to log in after clearing all my cookies, but the new email verification never arrives. I've tried after an hour, and even after days, but I doesn't work. I never get the verification email, not even in spam. I have contacted support through the website, but no response either after more than three weeks. Also the chat doesn't work no matter what browser I use. I'm guessing there must be some deliverability issues. For some reason I can log in here, but not on the actual platform to use it.
