[Resolved]  HDFC Bank — hdfc cashback not received

I have bought my iphone11 with hdfc bank credit card - 6 months emi on 19/12/2019 in gurgaon. As mentioned by hdfc bank (To receive cashback of 6000 within 120 days from the transactional month end) i haven’t received my cashback till now, it is more than 120 days. Hope this issue gets resolved and cashback will be credited as soon as possible since my credit card is going to expire in june 2020. Need quick help on this one.
