In May this year, I travelled to England to visit family. I normally do this every other year. I always hire a car and did so this year, in fact 2 hires, both using rentalcars.com. When I went to pick up the first car at Heathrow airport, I was advised that there was no car insurance on the vehicle and that I would have to buy insurance before I could take the car. This left me no choice as I had prepaid the rental. The insurance ended up costing $1316.48. The 2nd hire had standard insurance included with an excess of $1500 (which I always insure in Australia). I contacted rentalcars.com via email the following day and many days since all to no avail. The story according to them is that it is my fault that the booking went through their US systems and did not include insurance as most people hiring in the US have insurance with their credit cards. "Please be advised that the location you made your booking from depends on the IP address used to make the booking, which is detected automatically when you access our website. How do I go about suing them? Can I do it through the small claims or do I need to use the UK system?
