You pay for nothing -please come again

About 2 weeks back I stopped at Total -Wonderboom south -on the corner of De Beer and Steve Biko , I asked the man to please give me R200 93 , he finished -and as I left I found it strange that my petrol Gage did not lift , I worried about this and thought there might be something wrong with it , later in the week I looked at my petrol Gage and noticed it was going down , with a shock I realized he never put any petrol in to my car , I have been going there for years , so this came as a massive shock , I feel taking clients for fools and committing ***** -should be reported to their head office , and I have done that , with no response , that tells you everything you wanted to know
