Kalyan Jewellers — Excess value addition charges and insurance

Address: Mumbai City, Maharashtra

My wife Deepa Murli purchased earrings from Kalyan Jewellers vashi on 5/8/2015 bill number VASGJC007239. The value addition on a small piece of earring is 22% . The jeweller is not mentioning making charges or wastage and simply adding 22% . Most jewellers charge 11 to 12 % . Also the salesman has asked her to take some insurance on a 3.86 gm jewellery. On a small earring a VC of 22% is ridiculous
