unfair trade practice

On 18th Sept.2017 I purchased various items that included ready made clothes & one suitcase of skybag make from Brand Factory,Tardeo,Mumbai on various rates of discount offer ranging from 20% to 60% on MRP. I paid Rs.Rs.17086/- ( Rupees seventeen thousand eightysix only).But when I verified their retail invoice I found that the retailer manipulated the price ie instead of allowing discount on MRP, they added GST@5% on the MRP after discount.I am giving below two examples:-
MRP – Discount offer – Price after discount GST Actual Paid
on MRP
1) 1399/- 30% – 1259.30 – 62.96@5% – 1322.26
2) 8640/- 50% – 4320.00 – 226.00 @5%- 4547.00
When I protested the Brand Factory executives refused to listen my plea. .
Everybody is aware that MRP includes cost+Margin+Taxes,hence charging GST on MRP amounts to multiple taxation which is a unfair trade practice with malicious intent to cheat customers by advertising false offers over & above it defames& denigrates GST & defeats its basic objective.
I therefore request to direct the retailer to henceforth desist from unethical trade practice,refund the excess amount charged & pay suitable damage to me for entering unnecessary argument & wastage of my time at payment counter.
Yours sincerely
