Green Motion Kenings *******

I hired a car for 3 days from them at Cape Town airport and prepaid R1700 for that. I later phoned them to ask if I could extend the rental for 4 extra days and the guy said that's fine. I said should I pay now and was told I could pay when I picked up the car. I picked the car up and the charged me R3400 got the extra days. I thought that was a a grand too much but let it slide. Low and behold they then 4 weeks later to another R2500 off my account to pay for the extra days. When I queried why they said the extra days were R1300 plus vat per day. What a *******. I did get my deposit back quickly though but I'll never use them again.
