AMAZON PAY ICICI CREDIT CARD NEGATIVE REWARDS

they do that regularly when we have many refunds going to next cycle of billing, nothing new in that

This is normal. With every billing cycle, they calculate the CB and credit it to your Amazon Pay account in that billing cycle. If in the next billing cycle, you received refunds for the items purchased in the previous billing cycle or they mistakenly gave you say 5% CB instead of 2%, they will keep adjusting the extra CB credited to your Amazon Pay, i.e. you won't get any CB until that extra CB already credited to you is adjusted.

But In December It Was Minus 64, In January’s Statement Its Minus 338..

So I’m Confused… What to do Now??

the negative balance is due to the error in their system. Similar thing happened to me, merchant refunded the amount for a cancelled transaction and the ICICI deducted the rewards for that credit amount whereas for the debit transaction amount they have not credited any rewards at all so instead of net reward points of a refunded transaction to be supposed to be neutral, we are accruing negative balance in rewards. That I came to know after going through the rewards statement obtained through their customer care email.
