I had ordered a product online and it was delivered to me at ₹0 because the price was ₹0 when I had ordered. I even had received a confirmation call from the company before they shipped. They didn't say anything about the pricing at that time. But when the item was delivered they are demanding money through gpay without providing bill. What should I do?
You may either receive it by paying through GPay or just return the same. But, you cannot get reimbursement of your payment after paying the amount. That is tactics of business people putting you into embarasement.
