[Resolved]  HDFC Bank Bank Ltd — Hdfc bank cashback not received

I purchased 15k worth of clothes from the US Polo store, Hyderabad Srujana Forum Mall on 29.11.2020 12.35PM ending with my card No:0349. At the time of purchase, we have been told that there is a Festive Treats offer of 10.% cashback on HDFC credit card. Cashback was supposed to be credited within 90 days in my credit card account. But now it's been more than the said duration and still I haven’t received the cashback on my purchased amount. I complained to HDFC customer care so many times but there is no positive response & every time they told me to wait a bit more. I request you to kindly provide me the cashback at the earliest. i already sent mail two times but there is no response.
