If you had placed an order previously by applying a coupon code; however, you didn't like it due to any reason, you will get only the money refunded that you spent after applying the coupon code. In simpler words: you won't get any amount for the discount code. Additionally, the same coupon code won't be applicable in the future on any orders. It cannot be availed again.                                                  
  For example- If you had placed an order of INR 1000 and applied a discount code of INR 250, in actuality you spent only INR 750. Just in case, if you wish to cancel the same order, you will get INR 750 reimbursed and not the coupon amount. Plus, this coupon code won't be valid for further orders.
