sandhu computer

I gave my laptop for powerpoint repair to sandhu computers. I was promised the laptop will be returned to me in 3 business days. but it was retunred to me after 10 days that too not properly repaired and another part being broken.
When i complained they initially refused to acknowledge the brekage.
Also, i did not see the main person who owns the business, and hold the certification for computer repair, to be working. Each time i visited there were his teenage children working and fixing(or breaking, as in my case) peoples compters.
I will never receommend abybody to goto them.
