Worst service ever

<p> I arrived at King Shaka airport on Thursday 26 May having booked a car via Mango with Avis. On arrival, I was told that my account had been marked as a security risk and that they could not provide the car I had reserved. I spoke to two men, one of whom said he was the supervisor and they reluctantly called the head office, then told me that there was nothing they could do, as the accounts department was closed and they were not able to provide me with the car I had reserved. They were rude and unhelpful. I was forced to rent a car at twice the price from another car company. The following day, I called Avis to be told that the security alert was incorrect and that my account was totally clear. I wrote to complain and tell my story on the 27th May. I called back on 1 June to say that I hadn't heard from them. I was told that they were busy as it was month end. On 2 June I was told that my complaint had been escalated to Anita Burger. I have still not had the courtesy of a response from her. Avis has the motto "we try harder" That is not my experience. They couldn't care at all.</p>
