Big Bazaar / Futurebazaar / Future Retail / Hometown — gst charge on discounted item

Address:

Dibrugarh Assam, 785670

Dear sir
I have purchased an item from their outlet at dibrugarh assam on 08.02.2020 whereby they offered me a discount of 40% on mrp (Rs 699). After discount it's price simply ought to be rs 419.40. But to my surprise they asked me to pay rs 440.38. While enquired they replied that 5% gst has been charged on the discounted price and i have to bear the same.
This act surely amounts to unfair trade practices and cheating lakh of coustomers in an indirect means.
Thanks with regards.
