Bad/misleading advertising and rude treatment

Fairlands Smit street total filling station ****. I drove more than 2km chasing a gas special that is advertised at corner Beyer's and monko road. I got to the shop and there was more than R100 price difference for a 19kg gas. The franchise owner/manager treated me like a crazy person and argued with me that he had put the billboard/trailer down. Eventually drove with me to go see the add. After driving to see the add. About 300miters away. His argument was "but we are still the cheapest" in a condescending way. I feel ****** and ill-treated. That was the last item Ill buy at Total.
