Like many others, I had a terrible experience with Tempest

Like many others, I had a terrible experience with Tempest. First off, they charge R500 more for an upgrade done in-person than a new booking online would cost. Secondly, the staff at Bloemfontein Airport where I returned the car had no interest doing a final inspection, and advised me it's not necessary, only to email me a week later about damage on the car and that I needed to fill in an "Incident form", even though nothing happened to the car! A week later and they are still busy with an "investigation" (which I would not have known about if I didn't follow up, and that could only take a maximum of 2 minutes to look at photos), and keeping my deposit money. This really reeks of *****ulent behavior and I suspect they are taking chances like this all the time.
