Terrible service

<div>I booked a vehicle weeks in advance and requested an additional driver as an extra. I paid the full amount. Later I removed the additional driver (worth ~R500) and decided to rent a 2nd vehicle.

On the website and on the phone call with the call center I was informed I would receive a voucher for the additional driver and I would be able to apply that money to my 2nd vehicle.

When I went to the Airport to collect my vehicles, they couldn't find anything out and they said I'd have to call the call center to sort it out & I would get refunded the voucher value when I return the vehicles.

My vehicle rentals went fine without issue. but when I returned my vehicles I was not refunded any amount. I called the call center and the agent put me on hold, promised to call me back multiple times but NOTHING has happened</div>
