Superlative "After sale" Customer care

I rent vehicles often and know that things do go wrong as rentals go. Agents also deal with their customers differently. As we are humans, we all make mistakes. I believe it is after the initial rental agreement has been signed and something is not 100%, that the difference in customer care is the differentiating factor! In my case, I meticulously check the vehicle for visible body damage and the windscreen for possible unmarked chips. What I have never checked before, is the fuel gauge - it is a given that the tank will be fuel, right? Well not this past Friday at the cape Town International branch. I had driven 38 km when the warning light went on to tell me that the petrol was exhausted. I was horrified as I had initially planned to drive through to the "platteland" and eventually could not, but it would have been a major issue if this had happened on a deserted road. It didn't. I drove to my hotel, called the Woodford Customer Service line (Again an improvement I recommend - if a number is given as the "direct contact", the phone should at least be switched on! I was only able to get through to a customer care representative upon the fourth number I tried), spoke to the agent and had the rental vehicle replaced within just over an hour - and this on a very busy Friday afternoon....it is this "post-sale" customer care which will have me use Woodford again and again. Peace of mind and secure in knowing that, if things do go wrong, it will be attended to.
