Tasmac — They charging usally higher

Respected sir,
I went to buy a black pearl beer which MRP is 130RS. they charge usally in all TASMAC shop 140RS which is already higher but this time they are charging me around 150 when I ask why they are saying that if you need then buy otherwise move.I said ok give me tuborg they said its price 170RS. I really shocked, they were selling all beer in higher price around 20RS
It's not fare nah.if they charge like this means that single shop which is located at karur(TASMAC SHOP NO:4908) that shop sells 200 beer per days if we see yearly they are get around 14lakhs.plz take the necessary action sir.
Actually sir this total money can be saved and each penny matter to all our citizens.
