[Resolved]  HDFC Bank — hdfc bank iphone 11 cashback not received - past 120 days

Hello,
I bought my iphone11 with hdfc bank credit card on 23/12/2019 at reliance digital, vashi, navi mumbai 400703. As mentioned by hdfc bank, i was to receive cashback of 6000 within 120 days from the transaction date. The time frame of 120 days passed on 23rd april 2020.in fact it's 120 days past the transaction month end as well. I haven’t received my cashback till now, it is more than 120 days. My latest statement dated 3rd may 2020 did not reflect the cashback. I checked with reliance digital, they asked me to inquire with the bank. I tried calling the bank over the helpline, but they are not entertaining queries like this one at current time.
Hope this issue gets resolved and cashback will be credited in my credit card statement as soon as possible.

Thanks!
Abhijit
