Fuel discrepancy and bad service

serves as an inquiry on the treatment received from the supervisor put in place kindly see attached as supplementary to this email I’m sending this email upset and disrespected by your supervisor Booysen at the Cape town international airport branch on my arrival I got the best service from SIBU the sales agent at the front who was nothing but the best. The concern I had was that on collecting the vehicle it was filled to 540 km from the office as per the picture of the cluster sent on receiving the vehicle. On return, I then filled it, and the tank came up to 570km on the cluster as per pictures sent on the inquiry. By (Booysen), I was told that I don’t know how to fill a car up as they fill up at the depot. I was then educated as if I’m a total idiot in front of my wife and other customers on how a car should be filled up, which I was inappropriately shown the door by the response received.
