You have not mentioned one more hitch in this schemes.
ICICI bank have floated the 5% cash back scheme. I availed of it.
They gave me the cash back also after 1 month, but they slashed 75 points from my earned rewards points. This was never informed before hand & is wrong on part of ICICI. In a way by slashing the reward points, they have pocketed back some money out of the 5% cash back.
bank thinks customers are fool. But i have noted their foul play & vow not to use their card ,as far as possible.
