Dell — False product information and bogus product selling instead of stop the faulty series

Address:

Ahmedabad, Gujarat, 380015

I have bought a dell alptop 7 days back dell 5559 series fullhd 1920*1080 resolution
as soon as I started it there was a patch on screen wifi card is not working properly
videos are blury
writing appear blury like when open device manager or on internet explorer some part appears clear and some part pixels are blured updated drivers everything still not solved any problem even the video are not clear after spending 62000 approx. on these laptop for fhd vision I get blury video and blury writing

went to dell the representative told me that every 5559 series full hd laptop has these problem the writing would appear blury only
SO IF DELL ALREADY KNOWS THESE IS THE PROBLEM THEN WHY ARENT THEY SOLVING THE PROBLEM OR THEY SHOULD DISCONTINUE THE PRODUCT INSTEAD THEY ARE SELLING IT OPENLY AND ALSO MARKETING ABOUT ITS FULL HD CAPACITY
