Disrespectful behavior from fueler and manager

I'm a usual customer at your richards bay meerensee branch. Service is normally poor. However the disrespect I received from one fueler by the name Sibonelo and the manager today is despicable and embarrassing. I called the manager to intervene, but he didn't entertain my complaint. If that's the kind of attitude you guys allow us as customers to be spoken with then you will lose them to the new garage just in front of it.
