Bad service

On Sunday I went to twin City Bloemfontein mall to but some clothes for my child I was not aware about the time so I went to Ackermans in twin City that guys close the door right in front on my face without any word and he ignored me as if I was not their so I waited to tell him that is too rude to close the door like that in front of my face he could have just told me it's late they are closing I am a human being I would understand but he never looked at me I think they must be told customer service I really felt like stupid
