I was discriminated against by a large Texas grocery store chain when mgmt assistance was requested by me after being assaulted by another customer

I am a white female who was assaulted by an african american female in the check out line of a grocery store. I asked for assitance from managment and the store employees assisted the african american woman and ignored me. I was slightly iniured and visibly shaken by the experience. I had my minor child with me who had to experience this with me. When I filed a complaint with the store, wa dismissed. I file a complaint with Corporate and the complaint was sent back to management at the store level. When speaking to store management again, they refused to acknowledge the discrimination.
