[Resolved]  Big Bazaar / Futurebazaar / Future Retail / Hometown — deduct amount more than the total bill amount

On 26 jan 2019, i purchased grocery from big bazaar and some of the cashier employees were billing through a mobile phone for the customers with limited products. So i went to these cashiers with my colleague and split the products into 3 parts to avoid the waiting time of long queue. The bill amount was

1039.78, 1066.30 and 444.00 and the deducted amount was 1058.19, 1085.17 and 451.86

I raise this concern to my bank but they replied to confirm this from the merchant.
