Byjus — Cancellation and Refund our money

I had purchased course for my daughter for 5th-7th Standard at 15-20 days before and got the tablet and study material after 7-8 days but now I want to cancel the course as my daughter is facing too much pressure to do this course and raised the concern 1 week before and taken only 3 classes. At the purchase time, Counselor forcing us to take the course to check for 15 days and he was committing to you can cancel the if the course will not be fruitful for us and they will refund our money. we were asking to give us the time to think to buy this course. Now when I raised the concern after that every time they are just giving us 48-72 hours time. Please resolve this issue asap
