I have bought my iphone11 pro max with hdfc bank debit card on 01/10/2019 in ipixel hubli. As mentioned by hdfc bank (To receive cashback of 7000 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 ipixel, they said to check with bank. Hope this issue gets resolved and cashback will be credited as soon as possible. I called bank 2 weeks ago, they said me to send a mail to customerservices. [protected]@hdfcbank.com. They havent replied to my mail still. Registered mobile number - [protected]
