****med by Avis and mistreated

Before traveling last year, I hired from Avis OR Tambo for long periods however, I was ****med by Avis as they took deposits 3 times at least which they never refunded back to my account. I have sent whatsApp messages to the attendent who processed all the bookings, however, he ignored all my messages. He also requested for a cold drink which I gave in his hand then. I have also sent emails as international calls are pricey, to my surprise no one was interested in helping me. What a terrible experience with such a reputable company. Makes you wonder just how many people have fallen victim of the same issue. The attended asked a few times as to when I would return to SA before assisting me, which I never understood where that fit with regards to the deposits. Before leaving, I went back again as there was a query with the booking and extension, he was not at work, a supervisor who assisted me kept going outside to speak to the initial attendent, he could not assist me I assume after they found common ground on their share of the deal, I suppose. This affected me in a massive way, since I was trying to settle in in a new country. So I had to choose what to pursue at that time, to avoid a nervous breakdown. Really let down by Avis.
