Woodford: shocking service and excessive fuel charges

Based on good online reviews, I took a chance on Woodford (whom I had never heard of previously) for a recent car rental at the Jo'berg airport. I wish I hadn't. The booking was fine, but upon arrival there was a huge line. None of the other, many car rental places had a line, just this one. Eventually, the actual car and rental were process were ok. The return is what got me -- we opted to not refill the car since there is a R75 surcharge to top off regardless. The attendant confirmed that the fuel cost would match that at the pump. So, we opted to return the car with a 1/4 full tank. This is a KWID, specified to have a 28-L tank and get 4.7 L/100km. We were charged R703 (30.5 L) of fuel. To query the amount filled and the disconnect wrt tank size, I wrote to the reservations WhatsApp (which it said to do if you have issues). That turned out to be an auto-numbered-only reply which directed me to a second WhatsApp. I wrote to the second number, and was told to send email. I sent email and within a day or two, I got a response from a person. The response? "Fuel is expensive" and the cost was commensurate with the distance driven. Doing the calculation, a total of 39.2L were filled and we drove 487 km. That means that they filled > 30 L (on a quarter-full 28-L tank) and thought 7.7L/100km was reasonable consumption. They don't talk facts, just wave their hands. I won't use them again -- and if you do, fill up before returning!
