Stole my new indicator light and shoe polish

I took my car for a wash. At the new caltex service station. I left it there for a half hour. I then came back and payed for my car wash. Little did I know that the guys had actually stollen my brand new indicator laps witch I had just purchased. They cost me about R300 and they stole my shoe polish witch is another R100. I spoke to the owner and told him what had happened. He said he will look on the cameras. I told him how can the cameras see them inside the car. I said I know that the stuff was there when I left the car with them and now it is gone. He took his staff side over the client. He then started atacking me verbally over the phone. Caltex was my preferred garage to fill up. I will never go to another branch of there's again. Thanks to glenanda caltex
