I am a premium user. I have been using this app for 2 years. But two days ago, my premium account stopped operating. I did not know why. I changed a different payment method by providing 3 different cards (2 Indonesian cards, 1 US card) but my payment was always declined. I already sent an email to the office, but until now, I haven't got any reply. Please help me fix the problem, and I will change the star to five since I need it for my upcoming event.
