Disgraceful staff

I was shopping at makro. We had 2 trolleys and the invoices were also separate. My husband checked his stuff and they pushed him out literally. I came to check my stuff and tried getting the invoice from my husband and the security went wild. Pushing and shoving us. My four year old child was petrified and started crying the one security says I don't care. Really is this how fidelity staff are trained to treat customers Then to make matters worse the female supervisor starts yelling at me saying I said you black people. I mean really? Are they taught to look for every opportunity to use the race card. I was not even thinking along those lines but was more angered by the behavior displayed and my child being traumatized. I want feedback and an apology.
