Be careful when you use fraud website called Freecharge. Freecharge comes up with many marketing gimmicks wherein they tell you cashback upon recharges (50% & more).
I fell victim to this cheaters. I did the recharge on their website along with some coupon code.
However they never gave any cashback credits.
Upon raising complaint, customer care is claiming that I never used any coupon code. They are also refusing to refund the money.
They give various cashback offers etc, which never works. They simply take the money from you for the transaction & do not give back any cashback.
