Dell India — Dell Inspiron Issues - No proper technical support

I bought this new Dell inspiron laptop a week ago and from day one i am facing some or the other issues with the laptop.
Start, WIFI buttons not working, none of the apps are opening, fan is very noisy, no sound/volume.
Whenever I contact Dell support they message me some user manual and videos to follow. I spend whole day understanding the user manual and learning from videos and try the fix, still the issue will not be resolved.
Tomorrow same, they will send me some other user manual and videos. This is happening for a week now.
