But it doesn't say anything about vps holders who has to return the vps because either it's not working or unresponsive like in my case. It's find reducing 100 points of someone cancel a good vps so he/she can request a better one at next give away. But what if it's not his fault but the server or providers ?

Please check the bottom most part, It do say about the VPS Holder who wants to return/cancel there VPS.

Also what happens if I keep the vps and then request one in next give away and give up current one if I win the one I want ? As per current rules I won't be cancelling the vps so 100 points won't be reduces also if I win from give away again I wouldn't loose 100 points would it ? So basically that way i can replace or exchange the server without loosing points.

Yes VPS holders who wants to exchange their VPS, they can opt for it in the next Giveaway and can get a new VPS without any credits deduction.
