HDFC Bank — Cashback not received

Address: Hdfc bank

I have bought my iphone11 with hdfc bank debit card on 31/01/2020 in invent greater noida . 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. The help desk of hdfc is also not responding. I think i have been made the victim of fraud. Hope this issue gets resolved and cashback will be credited as soon as possible.
