Also paxful is not a scam as it's simply a platform. Sure there are users that scam on it but the same thing can be said for localbitcoins as well
OP did not said that paxful is scam. He simply can't use it since there aren't much orders of ETH to INR.
With research I found that you can directly trade INR to eth @ buyUcoin and Ethexindia.
If there's no other option, have you tried using zebpay and just buy btc then convert to eth?
