BP GARAGE TOM JONES ROBBING CUSTOMERS

I went to BP garage Tom Jones on Sunday and asked for full tank. My petrol tank was quarter full before I poured the full tank. The amount I paid for full tank was R300, which was confusing for a petrol tank which was close to full. When I started the car,my petrol gauge didn't move at all from where it was, I switched off the car and started it again and the same thing happened. I left assuming that the petrol gauge will pick up as the car moves and nothing happened. I reported the matter the next day and nothing much could be done, cause on the cctv the petrol attendant is seen pouring petrol and being assisted by another colleague to check oil and water. When I check the reviews the same problem happened 6 days ago to another customer and the issue was not addressed. Clearly the management and the workers are working together in robbing customers....
