HDFC Bank — It’s more than 120 days and still no cashback

Address: Reliance Digital,Elante mall ,Chandigarh

I have brought my iphone 11 with hdfc bank debit card on 26/01/2020 from reliance digital, elante chandigarh. As mentioned by hdfc bank to receive cashback of ₹6000 within 120 days from the transaction month but i didn’t receive my cashback till now. It’s more than 120 days so i hope this issue will be resolved and cashback will be credited as soon as possible.
