My son did not book classes for few weeks as he was preparing for his school exams. Surprisingly they automatically booked the classes without even notifying us and marked it as expired. When we tried to reach pit for help, it was veey difficult to find support on call. When we weote mail they declined saying nothing can be done. You will face this challenge if you have any issues with them, you will not find anyone to discuss your problem and seek solution. They will be very active while selling on calls and WhatsApp. But once sold and fees paid they disappear. Pls be careful
