Hello, i have purchase dell laptop from its official store in tear 2018 and i have purchased system which have preloaded windows and everything. From the day 1 i am having the issue in system performance as system is very slow as its takes very long time when i start and after starting i am unable to use the system as i have went 2-3 times to the same showroom but they said try to update system then use it. I have update system fully but my system is same as earlier. I tried to contact dell service many times but they say to run diagnose every time but its not resolved i asked them to gave me a address to their official service centere so i can go and show my laptop performance to them but they won’t give and always says me something to do by own. I have made multiple request on there call center but they are just ignoring the issue and says to run on safe mode and all. I had tried every measure to make it fix but they are not give me a correct advice but they are also neglecting the same. I had very bad experience with dell really disappointing with there service.
