Bad Customer Service

I arrived at Family Food Center on Tuesday and while I was waiting to get my groceries some Hispanic lady approached me all nice. Once I was done purchasing my groceries I asked her for help and she said yes with an attitude. Then she started talking in Spanish with another lady that also works there and I heard her say "superviosora" and she profane in Spanish. Then she laughed out loud and I heard her making a remark about black people. She said "negro", which made me feel upset because I'm sure she meant it as the N word. She helped me take my groceries outside but she left them on the ground. A stranger had to help me out because he saw my situation. I hope something gets done because I don't think I deserve to be treated this way. Please, please I hope someone reads my complaint and something is done... because it's not fair to get treated this way just because I'm handicap.....
