Bad bad bad experience

Since you took over from Regent, its been chaos after the other. I had an accident in July the third & since then I have had unpleasant experience with your service. You hired me a car, the reservation was extended due to the fact that there was a delay in authorising the panel beater & I have written confirmation pertaining this extension. Now the rental company went & debited my account with R3000 because you have not paid for the extension, this is ridiculous, how is this my problem. Please urgently deal with Europcar because I need my money back.
