I have complained the same through the email i got the reply saying the money gets refunded within 5 working days but now today it's 7th day still my money didn't got refunded. I have called so many times to the customer care but it was too worst that every time it says call waiting. Please tell me some solution to this to get my money refunded. Thank you. Please.
