One of your store in haridwar near multan sewa sameeti dharamshala operated under guru kirpa dhaba is charging more than mrp.
I went there to buy a chocolate of rs 35 on which they charge me rs. 40 by saying that they charged 5 rupee for their tax.
I don't understand how could anyone charged more than mrp when all the taxes are included in mrp
When i asked him why he us charging so he told me that if you want to buy, you have to buy at this price only otherwise leave it.
Actually there is no other ice cream store nearby and maybe that's why they are charging higher. I can also go to consumer care center.
Please take my complaint into consideration and control this monopoly ruling here.
