Big Bazaar / Futurebazaar / Future Retail / Hometown — Request for Cash Back against Purchase wide invoice No. [protected] Dt. 23.01.2022

Dear Sir,
I am in follow up with you since long time and make contact to Paytm as advised by you, Paytm denied to such offer given to big bazaar, but I seen offer (I have picture) into your store and same explained by your representative. Now tell me what I should do in this situation. I purchased product from big bazaar not from road side shop. Now I have doubt into big bazaar honesty on the offer display. So please consider cash back this time otherwise I have to go legally with you people because I frustrated now as I visited personally big bazaar to redeem the offer means I tried to not to took this case into public platform as it is matter of very amount.but now you keep on saying as offer from Paytm only so contact to Paytm here my question is why big bazaar not supporting customers inspite of saying only. How many times you have confirmed from Paytm about cash back.
I am very clear here this offer pasted in big bazaar so it sole responsibility of big bazaar to to avail this offer either from Paytm or from Paytm but customer should not suffer in between.
If you can to resolve it let me know your customer grievience redressal mechanism.
