HDFC Bank — HDFC Bank iphone 11 cashback not received

I have bought my iphone11 with hdfc bank credit card on 05/04/2021 in from the Imagine, UB city store in Bangalore. As mentioned by hdfc bank (To receive cashback of 5000 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.
