Dell — bad after sale sercise and less service center

I purchase dell ceneu 7 tablet in sep 14 . after few months it start showing some screen problem .after that I visit 8 time to their service center but problem is still in it . i spend alomost 2500 on fright and waste 8 days and I'm from patiala and there is no Dell's service center so I have to go to Chandigarh for service . this company only believe in sale not after sale service please pass a rule against them .if they want to sale everywhere they have to open at least one service center in every district . other wise they can sell their products in only those cities which have their service center .
