HDFC Bank — Regarding cashback

Address: Malegaon

I have bought my iphone11 with hdfc bank debit card on 15/01/2020 in reliance digital store in malegaon. 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. I have asked in reliance digital store they said to check with bank. Hope this issue gets resolved and cashback will be credited as soon as possible. My contact number is [protected]
