There are 2 Human Rights offices in Qatar. The National Human Rights Committee (NHRC) is located near Jaidah Tower, NBK intersection, behind the Teyseer petrol station. They offer good advice but I have never tested their ability to take action.

It's better to go to the Human rights dept. of the Ministry of Interior. This is located on Al Markhiya Street near Jassim bin Hamad School. They helped me out a lot. Try them and good luck!
