Big Bazaar / Futurebazaar / Future Retail / Hometown — no discount because of 2 bills

Hi team,

I did big bazaar shopping yesterday and at the time of billing the billing person told me that there is a offer on paytm. The offer is if we pay by paytm on doing shopping of 3000 we'll get rs.600 cashback. So we did the same. We had done shopping of more than 6000 so he split the bill under[protected], which is appreciable. But that time mistakenly the offered item got split up and separated in different bills and because of that we were unable to avail big bazaar offer. Like we had offer of 'wild stone deo' with offer buy 2 get 1 and same thing happened with cold drinks, we bought 6 cold drinks to avail buy 2 get 1 offer two times.. But unfortunately that cold drinks got split in 4 and 2 then again we failed to avail the offer. Can you please help us to avail these offers back...
