Disgusting ****** by Truworths guard

I just visited the Truworths at the Oval mall in Ladysmith. I am appalled and disgusted by the guards attitude. The closing time advertised is 5pm. It was before 5 and the door was closed. I tried to appeal to her, I knew exactly what I wanted, I would've still been in and out before 5. But she refused to hear me out. She opened the door for a customer to exit and slammed the door shut on my face. I still tried to talk to her and she blatantly ignored me. I am disgusted. I am a loyal customer, I shop there all the time. When I walked past the store 2 minutes later, she was explaining very politely to a black couple that the store is closed but I could not get the same courtesy because I am not black? I am disgusted, besides this being ****** is it not ********* for a customer to be treated in this manner? I will never shop there again!!!!
