Condo owner feels ill-treated by association board. What can he do?

I own a condo in Washington DC. My condo board association members are very rude, short with me whenever I ask of assistance from them. They say things such as "well, this is a free position and if you don't like how fast we respond, maybe you can run for the board next time". I really feel discriminated against based on race and religion and my question to you all is which agency in Washington DC handles complaints of this nature. Thank you, A
