Enterprise Customer, Can't Submit support request, support impossible to contact directly

I am trying to update the email address linked to my profile, but it throws a 403 error when I try to set the password after clicking the link in the verification email.

I tried deleting my Jetbrain account and creating a new one, but it somehow still logs in to this same account.

Can't submit a support request as it says my email address isn't verified... require help from Jetbrains support asap
