Europcar and Tempest car hire - customer service stinks

I have experienced a very emotionally traumatic time with Europcar. I was involved in a third-party incident with one of their drivers, many months ago. I was lumped with a damages claim of over R13000 for repair work that was not completely of my doing. I have been repeatedly harassed by their debt collection company. Even though I produced evidence of my portion of the damages, my protestations have been ignored. The list of repair work for that car is beyond belief. Be very very careful when dealing with Europcar and its sister company, Tempest Car Hire, as they will use ************ tactics to get people to pay for repair work to their cars for damages that you are not wholly responsible for. I also doubt anyone will even read or respond to this post. Perhaps the Consumer Council will be the best option. Although I do wonder if other clients out there have not had similar experiences but have been too afraid or intimidated and have simply agreed to 'pay up and shut up'. But it simply goes against the grain
