Pathetic service at Engen ma-africa Zola soweto

I drove to engen ma-africa in Zola soweto last night (19-12-2023) very late .l got there and I didn't have hard cash as I avoid carrying cash around.l asked the petrol attendent without a name tag purposefully to fill petrol for me and he asked if l was going to pay with cash or card .l said card ,he then told me that they don't accept cards when filling petrol but l can only buy inside the shop with a card.l asked to speak to a supervisor and the guy said he was sleeping and refused to go wake him up and my sister went inside to ask if we could speak to someone because I was very low on fuel . Everyone in that shop didn't have a name tag and they all said that it was management policy that they dont accept card payment.l left very disappointed because I had passed caltex and ran out of fuel .l had to walk close to 2km to the next garage.But of note is that this is not the first time am getting pathetic service from the same station .The last time I reported to their client website and l never got any reply.l just don't get why big companies like that have different standards for different areas because l know that in predominantly white areas they send surprise shoppers who help to monitor service quality.
