Security guard "Aaron"

I was walking through the mall in Westgate in Mitchell's plain when I realized that I had left my cellphone on the till in the i-click business center, I turned around and hurried back as soon as I realized my phone was not with me, as I was walking back a security guard tackled me around my stomach with both arms and squeezed me and said I have to come with him, when I asked why and he gave no reason, I told him I had left my phone in the store and he laughed and asked me what I have ****** from truworths, I said I have never been to truworths today, again he laughed and said "don't lie to me". I then began feeling dizzy because the man was squeezing my stomach and upsetting my peptic ulcer, I told him that he's hurting my stomach, he said " don't worry you are coming with me, when we got to the security office the supervisor spoke to him in Xhosa speaking and saying it's a false alarm, I asked him to identify himself by he's badge and he said "no" I must ask he's supervisor. All I wanted was my cellphone not to be ****** now I have to see a doctor because my ulcer is bleeding my stomach is burning inside. The only information they gave me is he's name "Aaron" and a landline phone number : *** the number for Westgate security office, I feel the way he man-handled me was way too excessive and the fact that he just laughed it off and said it was a false alarm I feel that they can just hurt people and say sorry we thought you were a ***** because you were in a hurry, I will open a case of assault as soon as I get to the police station
