[Resolved]  Dell — Laptop Touch screen not working

I purchased a dell inspiron laptop model 4209 C on 24 jul 15.The touch screen had some issues since day 1of purchase.But due to my busy schedule I complained about it to dell on 26 Aug15.They mailed me that I will get support in 1 day which I got in the form of e mail after one week.And then they initially told me that its a software issue and they took remote access and reinstalled some softwares.but to no solution.Then after repeated requests they sent an engineer on 24 th September and he reinstalled the windows and all the drivers and changed the touch screen but it did not work.The company is asking me to reinstall all the softwares again on my own and is not ready for onsite support as they say its not a software issue.But the softwares which I am using come preinstalled by dell and they say that they provide onsite warranty for hardware and they are not providing support for a non working touch screen which is a hardware.
