Tasmac — overcharging and threatening

Address: Chennai, Tamil Nadu, 600010

I purchased 12 kingfisher bottle mrp ₹120, 1 richmans rum & 1 signature whiskey 750ml for ₹520 & 760 respectively bringing the total to ₹2720. I made this purchase from the tasmac located at suntech city mall, purasawakkam and they asked for ₹2880 on my questioning them as to why they are charging extra and saying that i will pay with the hip bar app the guy at the counter suddenly becomes rude and says you cannot take a crate of beer so go and take 12 bottles individually and told me to get a bag from home for the purchase. There was a lot of altercation thereafter as i denied paying the extra amount and told them i will pay as per the mrp and nothing more. These goons are over charging everyone and nobody questions them as they become defensive and aggressive. They have over charged me always in the past 3 years that i have been going to them and eversince i got the hip bar app i have always paid mrp and they always fight with me when i do. I request that you look into this matter, this is utter harrassment in the name of extortion and is wrong.
