I have purchased a coupon of book myshow from magicpin worth rs.350. When i apply this coupon it shows invalid coupon. I have registered my problem to magicpin. They said it will be solved within 24 hours. But it has been a week i got no response from them. I want my money back as soon as possible. My bookmyshow voucher number : 8ce6kyftkq. I have paid rupees 175 from my paytm and 175 from the magicpin points. I want the money back.
