Topspin return on underpin serve

what should i do to avoid missing the ball with deep and heavy underspin on it while playing topspin mostly the racket moves over the ball missing the low bounce of the ball completely and also tell me that where to hit such shot on the ball either on the table or by standing away from the table allowing the ball to come out of the table after its second bounce? 

Hi Haseeb,

You need to move into the ball more.  The backspin will mean that the ball will stop on sit up a little more.  That is why you often miss the ball and swing behind or over it.  Therefore you need to move forward to meet the path of the ball.
