Charged for their own defects!

Woodford charged me for a defect in the seat that i pointed out to the car inspection guy. I noted that i spotted this on the day of hire as soon as i got home as no inspection was done on the interior of the car. When collecting the car, the inspection guy told me that damages smaller than a 10c coin (according to a sheet they use) are not considered. This hole in the seat is smaller than a 10c coin but i reported it anyway to bring to their awareness, and i was charged R5k for it!!! Four months later, there's another charge of R575 on my credit card and no reason for it! What corporate bullies! The treatment and experience has been incredibly bitter.
