I have upgraded to Pro Plan two days ago : Apparently a bug occured on the Typeform website : My card has been debited twice and my plan still in Free Mode : no access to the Pro functions. Ok. That happens. But i have emailed them and no answer received yet ! This is a business emergency and no one answer, for 2 days, no chat available, thats so unprofessional for an online service.Edit : I have received an answer that is satisfying for fixing my problem.
