Disgusting Unethical Trading

I had waited for almost a month for new hotwheels cars to arrive at the store. When the cars had finally come in I was contacted by a lady from the Springfield branch to inform me that stock is in. However, upon arriving at the store I was absolutely disgusted that a worker had taken all of the popular cars off the shelf for himself and thereafter the leftovers were left for the customers. When I requested him to show me the cars as this is unfair he walked away with an arrogant smirk.I had requested for the manager Mr Niel who was extremely rude and showed no sense of understanding me as a customer whatsoever. As I regular customer I refuse to shop at this unethical shop ever again.
