Dell India — wifi issue last 5 month

Hi
I have purchased dell laptop in november and from a same time i am facing problem with the laptop window 10 laptop is not able to connect with wifi
It automatically disconnect in 5 to 10 min i had called customer service your technician visit in my place but problem was not resolved i have uninstall and install window 4 or 5 time with the help of customer service. Now today when i called customer service that now idont want this laptop because from last 5 month u are not able to fix the problem what is the benefit of new laptop if i am not able to use that then the suggestion i got from floor supervisor that u can visit service center or i will arrange the call back from escalation team and telling me sometime issue take few days when i ask that from last five month why didn't u transfer me to escalation team he had no answer i asked how much time any issue take to fix he had no answer he was not able to resolve even a single query he had no answer of any question, so at last i had file case in consumer court and the case number is 660640. Express service code [protected] now i want to replace my product because from last 5 month it's not working properly so please replace it. And the floor supervisor who was giving stupid suggestion name is charan
