Pumping air instead of petrol

If the was a zero, I would rate it. I am writing to express my deep disappointment with the service I received at Engen Zaks Convenience Centre, Diepkloof, Soweto, on 07/07/2025. I visited the station with my petrol light on and purchased R200 worth of petrol (approximately 9 liters), but my vehicle's fuel gauge did not increase. The attendant, who was courteous, told me it would go up and advised me to call or return if it did not. However, after leaving, my gauge remained unchanged, and upon my return, it was showing almost empty. I requested to speak with a manager and was assisted by an individual claiming to be Sabelo Mchunu, who appeared unprofessional—no name tag, disheveled appearance—and did not bother to check my vehicle's gauge or investigate my claim properly. He suggested I return on Thursday, but when I did, I was shown a video of my vehicle with no evidence supporting my claim, and I was met with rudeness and refusal to assist. Instead, I was told to open a case. I paid for a service that was not rendered, and the station refused to refund or provide petrol. Additionally, management confirmed that this is a common issue experienced at this station, which further indicates a recurring problem. This entire experience reflects poor customer service, unprofessionalism, and a lack of accountability, which I find unacceptable. I request that this matter be addressed promptly and that I be compensated for the service I paid for but did not receive.
