I have ordered two products on 16 sept. 2019 on myntra but order is not placed and money is deducted from my account. I had paid from bank of india debit card of rs. 2892.96 but now myntra is not accepting this and they are only saying that wait your money will be transferred in your account. But still i have not got my money. My account on myntra is from [protected]@gmail.com. They have told me to contact my bank partner and bank partner has told me to fill a refund claim form. I had filled that form online as well as offline but still there is no any response from myntra.
