Dishonest Avis not recommended

One of the most obvious dishonest experiences I have encountered, was when I rented a vehicle from the OR Tambo Airport branch and returned it to Lanseria Airport the following day on 15 January. I took a picture of the odometer reading and truth be told, another 34km was added to the reading when I received my invoice the next day.. It has been 3 weeks and no correction was done, this after I have sent my proof via email and requested response 3 times already. I will not make use of Avis' services again and urge consumers to check the facts on their invoices.
