HP India — Damaged my product

Address:

Ratnam Enterprises, Amravati, Maharashtra.

I have gave my HP laptop to add SSD in it. They removed my CD player and placed HDD which was pre install at the place of CD player using "SOME CASE" and install the SSD at the place of HDD. My laptop was having "LICENSED WINDOWS". Each and every thing was told and shown to the person about the windows and all. When I went to take the laptop my first thing my "WINDOWS WAS NOT LICENSED IT WAS CRACKED" and "THE HDD CASE THEY USED WAS DEFECTIVE". I asked them firstly about the windows they told it was "NOT LICENSED". In HDD I was not able to download or save any file. So I asked them about the HDD they told its all well functioning but it was not they also saw the problem but restarted the laptop and told its all ok. I went again after using it for 2 days but it was not working. I was not able to download any software or any thing in it. I tried to take help from HP Support from Twitter but they also are unable to solve my problem. HP support told me to run some test and they found that its a hardware issue with the HDD. I have also send them the code and told them to talk to the service center but they told we can not talk to them you only have to talk to them. we have no writes for that.
They also lost 2 part of my laptop. There are some more problem. At last I want to get help from the service center as they defected my laptop. From one month I am in contact with the HP support on twitter. They are also not able to solve it. I only want that my laptop should be repaired as soon as possible.
Below I have attached the bill and the thing they lost from the laptop. they also lost 2 to 3 screw.
