Ordered a suit with an address of 1300, from Punjab Noormahal Subham Kochhar Silk Store, he said that he will get 4 days I called JB Main after 4 days, then he said the delivery boy has met with an accident, your parcel has been damaged, you will be refunded. He didn't even get a refund. He is telling me that if you have 8000 PR in your account, then only will it be refunded, JB refused, I got 5000 PR, then 3000 PR said 2100 PR, if it works, then it will not be refunded.
