Bad Customer Service Hertz Mthatha

I Have been a client for over 2 years with Hertz renting a vehicle month to month. I got my company to open an account with them. When one of their vehicles was scratched by a third party I sent the car in, opened a case for the third party. They sent me a bill for R35000 without even explaining what it was for> No breakdown given nothing but because I wanted to maintain a good relationship with them I advised I would make a payment arrangement for the repairs while taking out a new lease with them, The current lease I have been using for a couple of months, all paid up and never missed a payment. Yesterday they randomly called to say they are picking up the car due to the previous query with the previous car. So many ways how this could have been resolved. HERTZ Mthatha knows nothing about customer service and the staff do know how to treat people. Unfortunately judging by the online complaints it seems like it is a trend. The manager Dwight Isaacs could have handled this matter so much better.
