Habitat for Humanity complaint: Descrimination

Shannon is the manager at the location there
Me and a lady have a dispute on a glass window on who is the person to buy it

The lady said she was looking at the window first I said I will purchase if she is not sure She said she is Not Sire. I pick it up the window and she touch me on my hand and said to her Do not touch me please. We call the manager and exposure the issue The Managet Shannon after we explain the problem she act as a judge and Not explanation she was a-taking me
I told her my side but she did not listen to me all she did was listening the lady

I feel Discriminated because my English on try to explain to her with the best I could I am A Black Latino and strongly believe she did not care about my explanation
And did not also told me she was giving the lady the fight to purchase the window I have to find it out when the lady light at me and said Shannon give her the right to purchase it
I walk to Shannon office on the same location and I ask her why she did give the lady the Fight to purchase without a least tell me there the decision on the lady favor
She said she doesn’t have to tell me nothing Shannon was Not Nice
