Hp — It's a laptop or toy?

Hi team, I am not happy to writing this as I have purchased the hp laptop from well know merchant from flipkart in the month of this, the day I got the laptop was working fine but after 3 days it used to hang just after opening one or two tabs on chrome, same happened when I used to open one excel file it shows an error everytime not responding and after much time it used to open.

I have concerned hp customer care but they used to say that we need to just get it shutdown and resume the system or else I need to visit the service centre of hp.

I went over the hp centre and they have said that you have the (model Hp 15s) and it won't run with speed and not work properly and to make it run or work I need to add 4 to 8gb ram into it or else I need to purchase the ssd to support my system when I asked them to change it then they asked me to buy it from outside and they will get it install that too when my system is in warranty.

What kind of service is this and if the processor and supportable things are not in system then whats the point to sale such product.। have purchased it for office work but I am unable to do that.

I want to know where I am at fault I have spent my money with hp. I want to complain against the hp.

Take this system back or either make it work as I have spent my money not just for box which looks like laptop I need actual system not a toy to play with.
