Avis Cape Town ? I am not in any way surprised. Back in 2012 I was using them almost every month between March and August and every time there was some small unexplained extra charge when I checked my credit card. The excuses they offered were sometimes quite funny. Aside from the usual BS such as “damage” or “items missing” I was also told I had received a car parking bill but they had lost the ticket and a “City Tax” charge that never existed.
