It is always recommended not to keep your coins in any exchange as you are not in control of the coin address. Zebpay and other indian exchanges are almost dump one no one is good, it is much better to trade in localbitcoins as you are in direct contact with the buyer or seller and localbitcoins escrow system is very good.
Can you please explain how does this escrow system works? If govt stops the banking services to exchanges then only peer to peer will work but how does the payment and receiving work there?
You can find trusted escrow in this forum from these threads:

For example: My username is Guvn0r, it is easy to someone to contact you with a similar username such as Guvnor or Gunv0r etc..
