Monte Carlo Fashions — Product with manufacturing defect

Address:

110092

Purchased one jacket on 02.12.15 having size of 46 but bill issued for 38 size. The jacket was defective and was returned to their showroom at Pacific Mall but they did not issue any acknowledgement. Waited for so many days and finally forced to buy other products being refused to refund the money even after accepting manufacturing Defect. Purchase two lowers forcibly on 16.12.15. My question is why they did not issue receipt and why refused the refund? ?????????????????
