Nail polish crime scene

I have never felt so humiliated and embarrassed like I felt today at signature cosmetic shop. Walked in the today with the hope of getting my self a nice colour nail polish. Check through the colours which looked pretty nice. My budget was to get one +- 30rands of which it's possible because they always have specials. Just when I spotted the colour I loved took, took the bottle, to show to the sales lady and inquire how much it was, the bottle slipped through my fingers, landed on the floor and broke. I turned back looked at the sales lady, with such a sorry face. She just looked at me with a straight face and told me that the shop policy states that if you brake something you pay. Well I was shocked. I didn't do it on purpose, surely she saw that. In that moment she must have pressed a panic button, because all of a sudden I was surrounded by 3 security guards, with their walkie talkies, before the security guards walked in I had told her that I have no problem paying for it, if it was around my budget, which was 30 rands, that I took out and put it on the counter. With a ugly attitude she told me that the bottle was 49 rands and I can not go anywhere until I.pay it. Now surrounded by these security guards, I felt so humiliated , felt like a *****. I may not know a bout their policy, but I know for sure there is nothing like that, I have been to big retail shops, accidents like this would happen, but they never ever would treat their customers like how I have been treated in the store. I asked the sales lady Matilda to call the headoffice and allow me to speak to management and state my case, she got on the phone and spoke to someone who transferred her to I don't know who, but the right person was not reached. Only to be told I should wait how ever time to get to the right person. There I was standing there surrounded by this walkie talkie guys, one even stood outside the shop, waiting that I don't leave. I mean really. As I was waiting for I don't know what, Matilda decided to humiliate me even more, came out from the back office with a cloth and assign that I clean up the broken nail polish. Oh he'll no I wasn't going to dare. Just stood there waiting for her to summon me. She was still at the back of the office probably trying to get hold of management. I was starting to loose my cool now , demanded to get the numbers for their office and make the call myself. That's when Matilda came and said to me it's ok I can go. I am so disgusted angry and feel very humiliated by the action these women took towards a customer. It's was not professional at all. I am not just going to end it here , I feel I also need to contact the consumer board. Some may feel it was just petty money. Yes it was, but the feelings that I was subjected to, really makes me angry, I really felt like a hardcore ********.
