Airtel Payment Bank — cannot withdraw my balance to my bank account

I registered with airtel paymen bank (Apb) and i added 3000rs to the wallet immediately because i wanted to transact eith payubiz gateway which accepts apb wallet.
When i tried to pay using apb it says i cannot pay using apb wallet.
Now when i sent an email to the apb customer care they sent me this reply.
