HDFC Bank — HDFC Debit Card_ Cashback not received

Hi,

I have bought my iphone11 with an HDFC bank debit card on 11/07/2020 from Hari Om Custom Collection, Mumbai.
I was informed that I will receive a cashback within 45 days from the day of purchase and now it's been more than 3 months since I haven’t received my cashback.

Please find below transaction details as per the bank account statement :
Customer Name: Rutuja Salunke

Merchant name: Hariom Custom Collection
EMI Number: DC EMI LOAN#[protected]
Invoice No:00002050
Date of Purchase: 11/07/2020

Let me know if you need any other details.
Hope this issue gets resolved at the earliest and cashback will be credited to my account as soon as possible.
