Business ethics

My disappointment to Contempo Klerksdorp on their grand opening. I bought lot of items and requested the lady at store to assist by keeping it in front as they didn’t have basket. To my surprise when I got home some of the items were not there. Considering it was the last item I am assuming they kept it for themselves. What is disturbing me me is that I personally asked the lady to keep these items and they decided not to give me everything.
