Its one of the worst mobile payment site/app designed. Please dont fall for the cheap cashback offers.
You will repent on seeing the cashback amount. Its just not promising and you will get peanuts out of it.
Following things may help you understand cheap tricks.
Cashbacks are always mentioned "UPTO", which will be peanuts
Amount transfer to bank is highly charged than others
Amount transfer will never happen despite mentioning correct details
Promocode will be expired many a times
The offers would be always for Lucky user and definitely not you
Thanks
