HDFC Bank — HDFC Credit Card-rewards points redemption voucher not received

I have redeemed the reward points of my credit card ending 4793 for 2 Nos. of Joyalukkas Gift Voucher of Rs. 10, 000. The same is showing status as Dispatched. however I have not received the same. The docket number / tracking number of the consignment is not shared to track the shipment.

On contacting the hdfc home branch and customer care, they have raised the service request. But it is not yet addressed yet. They are saying the reward point related queries are not related to the Bank.

Requesting your attention and seeking redressal.
