Reliance Digital — Regarding cashback

Address:

Visakhapatnam

Hello sir, I jagdish singh rawat purchased a sony soundbar from visakhapatnam reliance digital in July 2021. During the time of purchase they informed me that there were an offer of 10% cashback if I pay through sbi credit card. But till now i didn't get the cashback. Continuosly calling the store people regarding that but there is no positive response. I want you to take necessary action.
