Khali dok var paay was ordered online with bookganga on 11th may 2019 vide invoice no.[protected] and i didn't get that book. I was surprised uptilll now i have not received the book nor the refund from bookganga whereas for the last 12 days. I am trying to get in touch with their higher officials but contact numbers is invalid. I have been cheated by the bookganga. This is highly against the ethics of doing business and uptill now i have not received the refund.
