So I've tried to join Premium for Students because I'm about to go back to university for the year and wanted to upgrade. However, when I put in my card details and attempt to proceed with the payment, it says:
I understand that I had taken the trial a year ago and cancelled after a few weeks, however I want to pay and join and am not interested in the trial. But even when I click the link suggested it displays the same message and will not allow me to join premium for students. Any help?
