Purchased a Dell 7020 Optiplex  from Amazon provider was Blair Tech. Warranty was 90 days. they did not offer extended warranty at the time?  97 days Into ownership windows Blue Screened..  and lost all my data, my system keep going into sleep mode and reset to default and again keeps blue screening.  I called Blair tech for help. First thing one gets once connected to Blair  is a promo stating you have won $100.00 ?? The person  or persons I called back several time same response.They come on and say, in order to process your gift we need to explain what you have won? I said I do not want any free gift numinous times I  just wanted Tech Support please. Was told we will connect you once we have gone over the free gift?  No thank you I said for the 4th time 3rd call , and they refused to connect me to Tech Support? As I said I called  back again  same response. I am so mad. I will never buy a computer from amazon again.  What a scam Blair is . I did not get my Widows 10 pro Key number either ??  So I do not have the licence for Windows 10 and now way to reload it said it came with correct installed only?Not possible to reload because do not have key . very very bad experience  I use my computer for work makes matters worse. Beware of buying without warranty.
