HDFC Bank — iphone xr cashback not received

I have bought my iphone xr on dc emi with hdfc bank debit card on 01/03/2020 by in jaipur with swiping my card on shop. 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 120th day today. I have asked to shopkeeper, they said to check with bank. Hope this issue gets resolved and cashback will be credited as soon as possible.
