HDFC Bank — cashback amount of rs 5000 on purchase of iphone xr still not credited after more than 4 months

In the month of december 2019, i have purchased an iphone xr model with a cash back offer of rs 5000. Payment was done through hdfc bank debit card and full payment was made. The purchase was done from apple store, diamond plaza mall, jessore road, kolkata.

The card customer transaction slip shows i am entitled for a cash back of rs 5000 and same will be credited within 120 days from the last date of the transaction month. Till date i have not received the cash back into my hdfc bank account.

My transaction id is [protected].

It is already 4 months and still there is no credit of the cash back amount into my account.

Please expedite to get the cashback credited into my account.
