Got billed for damage to a car - BEWARE!

Been renting from this company over 15 years without any damage to their vehicles. On last rental I did not notice damage to front bumper as I took a quick walk around (as usual). After rental, I get billed R3700 which I naturally queried. They insist I did the damage. I've been driving for over 30 years and all accident-free. Engaged with customer care and they tell me sorry, too bad, they did their own investigation and I am to blame for someone else's accident. They then try to offer a R500 discount...what a joke.

Beware of renting from Woodford, someday you too will be caught out even if it is not your fault. If this is how they treat their long-standing customers, then I will never return!
