Doesn't turn on,send It 2 times in warranty but they did not repair

Hi,i send It 2 times for a repair because my lapbook plus wasn’t charging and turning on. After a wait of Only 2 weeks for the First Time,It came back and the same day It had the same problem,so i send It again,this time i waited 4 months for It! It came Yesterday,It was working but It was not charging again! So now i Spoke with aftersale and they Say i have to pay for a repair because out of warranty. Are they kidding?of course i have to pay,i bought the PC a year ago,and they had It for an half of It for a repair. I Paid Even a lot to send It 2 times to Them,and they did Nothing! Please help i’m really angry right now .
