Disgusting treatment

I was walking towards the door step at clicks Westgate Mall and it was 2 minutes to 7, on a friday evening, my one foot was already in the store while the other one was still out the security stopped me and told me the store is closed, I stood there with so much shock that I'm being chased out, I was already in, I calmly told her that I'm already in the store, she however pushed me out and slammed the door on my face. I asked her to call the manager for me she advised she was instructed by management to close the doors and not let anyone in as they wanna leave. I shouted 'call the manager for me as the one customer was walking out cause I was ****ed that I got pushed out, the manager came and as I explained to him (Thulani) the manager he told me that it's between me and the security, I walked out cause I saw that it was useless to even speak to him as he does not serve his customers with pride and does not care how they are treated, all I wanted was for him to hear what the issue was and correct the security not to push customers irrespective of what her reasons where I never touched her she shouldn't have touched me either. Very disgusting.
