In India, online sellers were harassed by people who exploit these route. But since then, Amazon Flipkart banned some pincodes like in Delhi where scams were rampant. Normally, for such high value items, Amazon manages the inventory for a particular seller. In that case, if you don't have any proof or either trying to scam them ( I'm not judging but mentioned both scenarios) , your money is gone and they might close your Amazon account too! Small businesses which are new might scam the customers but that too is too risky as if customer has proofs Amazon outright takes the money from seller as a payback. Online selling is not what is used to be, stricter checks and open box delivery are used now. Show them proofs and they give your amount back as simple as that. I've faced same issue with cosmetic product and they asked for video and photos on email, refunded me same day.
