Kalyan Jewellers — high making charges @ kuwait maliya city showroom

Yesterday I purchased Gold from Kalyan jewellers. They charged me high making charges & cheated me. As Gold price is falling down they makes money with making charges and looting the Customers. As I have 6 months Installment scheme with them I have no other option to purchase gold from them. But t I request all the customers Kalyan is not good option to purchase jewellery.
