I would suggest you to use peer to peer exchanges. Localbitcoins is obviously the best, you can try BitBNS too. Or you can directly trade with traders who are trusted. Mainly in localbitcoins, many a times pro traders leave their WhatsApp number to contact to which you can contact and make direct deals 
Like I said before. USE LOCALETHEREUM instead.
Thanks for the reply guys .So which one is better? Localbitcoin or Wazirx?
I would say localethereum as it does not require ID. Acquire ethereum then Changelly / Shapeshift into BTC.
Reasons to consider LETH :
1. Non custodial - meaning you control your wallet.
2. Nominal escrow fees / service charge - Unlike LBC which charges a lot of fees.
3. Escrow works smoothly and you can even see tx hash of the escrow.
4. Based on Ethereum and hence tx fees are really low and txs get confirmed in seconds.
5. Most importantly, NO VERIFICATION!
My profile : https://localethereum.com/profile/legendster made over $5k in trades. So I really think you guys should give this site a shot.
