I had purchased a product from reliance digital store in December 2019 on cashback offer my HDFC debit card EMI. EMI was tenured the period of six month. I paid all the EMI in the month of MAY 2020. Reliance customer executive told me that you will receive your HDFC debit card cash on paying third EMI which was on 05 March 2020, but still i have not received any cash from reliance digital store.
