Car Fault

I haven't been using Woodford Car Rental that long and I don't use them that often either. However, the first time I used them, I was impressed with their King Shaka Airport branch. Sadly, I cant say the same thing with their OR Tambo branch. Their service is very slow and their system seem to go offline often. And nearly every car I collected from them had faults in it; firstly it was a VW Kombi, the wipers were worn off and not working properly, and a toyota urban cruiser and recently a new hilux, both these cars their aircon didn't have any gas in it. And with the urban cruiser I was almost in an accident because of the mist in the windows. Sadly, these things are not easily identifiable when collecting the car. You just realise when you start using them. I have raised these issues with them when dropping the car. Yet it seems it's a pattern. And this makes it very hard to trust their cars, for what are other underlying issues that these vehicles have that you're not aware of. Especially when you'll be travelling further away from their nearest branch, for they don't have as many branches nationwide.
