Dishonest & *****ed

I collected a vehicle at the Umhlanga, Cabana branch on the 27th of Sep ’22. The vehicle was received without a FULL tank of gas. I mentioned this to the rental agent, we then took a trip to the petrol station to “fill up”. They proceeded to fill up R60, but the vehicle was still dit not displaying FULL. I pointed this out to the rental agent accompanying me, but according to him the display doesn’t reach FULL. I left it there.

When I filled up the vehicle on 07 Oct ’22, before returning it, it displayed FULL?

I requested an explanation for the above, an email was sent on the 12 Oct '22. By 25 Oct I've still not had response from them. Rental Agreement Number : ***
