Diesel price was not adjusted as per news

Today (2016-02-03) i filled my car with Diesel seeing that it was announced that the price of Diesel was down from 12:00am with about R0-60c. When i got my slip i saw that i was still charged R11-30/L. When i quarried this the station management responded that the price for Diesel did not go down. I took a photo of the display at the Shell garage in DF Malan and it displayed Diesel at R10-21! i am outraged and seriously irritated for being ********** by a station which i support 80% of the time. i also ONLY fill up with Caltex due to the Standardbank reward system. How many other people get ********** as well?
