RBL Bank — Reward Points fraud

I have credit card with RBL Bank and I wanted to redeem my reward points with their shopping portal. I placed my order and redeemed 16639 points worth Rs 2995 and paid the remaining amount of Rs 113 with the card itself. However my order was cancelled by them soon after and they refunded me Rs 113 but they did not refund me my reward points.
After repeatedly mailing them and getting fake promises I am just tired and disgusted with their customer care. They even stated on 25th November when I lodged a fresh complaint that my issue will be resolved in the next bill cycle and my points will be reinstated. But its not. I am attaching the necessary screenshots for your reference. I request you to please resolve the issue.
