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.
