Reliance Digital — issues in billing and cashback

Dear sir/madam,

I bought grocery stuff from reliance smart dwarka from hdfc credit card on[protected], due to lot of stuff with me i was unable to check bill. I bought three catch masala 500gm each under the scheme but two get one free but i didn’t get that offer u charge me for all three same with cumins buy one get one scheme on that but u have charged me for two and another way i didn’t get 5% cash back as i paid through hdfc credit card my amount was 4602.46 and another bill 277.95 and your bill counter leady has told me that i will get 5% cash back on it.

Kindly resolve this issue
