HDFC Bank — Iphone 11 cashback not received

Address: Agartala

I have bought my iphone11 with hdfc bank Credit card on 09/02/2020 in Mobile Store, Agartala. 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
