Dell — dells after sale service

I have a complaint against dell, Acer, and other co . They sold product at all over India but when we talk about their after sale service its almost nil. 7 months ago I purchase a tablet of dell from dells authorised dealer and after 1 month it start some problem and they said I have to go to Chandigarh for service .I visited to their center abut 12 times because the tablet shows problem again and again and for every repair I have to visit two times one visit for leave tablet for checkup or repair and one visit for pickup tablet . I paid almost paid 3000 rs on fright but problem still in tablet .and waste 12 days .and I also warn them many times but they think i am joking . they provide home service to laptop holders . i am not so rich and in India their are many students like me which lives in those cities which are too far from dells service center . I just want that you pass a bill against that companies which only want to sale their products but not believe in after sale service . Please include that conditions in it If they want to sell their product they should have to open at least one service center in every district if they cant do that than they cont sell product in that cities or district Please sir this is my humble request to you
