Extra Vat charged even when MRP includes Inclusive of All Taxes

Location/place: hyderabad

Name of company/service: Shoppers Stop

Hi Sir,
I purchased few items from Shoppers Stop Begumpet Hyderabad. There was some discount sale. My total purchase was 1377.94 after discount. All items shows MRP inclusive of all taxes. They have charge 34.92 rs extra on behalf of charging VAT. So I need to pay 1377.94 + 34.92 = 1412.86.
My question is can VAT be charged extra on a product if it says MRP inclusive of all taxes.
If I am correct please raise my complain against the merchandiser. My cash memois 4510
Thanks
