Not Responsive and Useless

Never again will I ever use Tempest Car Hire again... January 2018, my company hired a car for me from Tempest due to my company car being repaired. The car was hired for the whole month of January. At the end of Jan, there was a gentleman that bumped into the back fender of the vehicle and when I called Tempest, they said to go to the police station so that I can file a report and get a report number. In doing so, I contacted them and they came to collect the vehicle and checked the damages and they said that they will be in touch. I paid R1 500 as a deposit on the first day of collection of the vehicle. After collecting the vehicle, they contacted me saying that i need to pay R3000 damage and I wont be getting the R1500 back until the insurance sorts out the issue. Just note that they kept calling and texting me reminding me that I owe them money and they will pay me all the money back . It is now November and I have not had any help from the company. I have provided all details, pictures and accident report number to Tempest and they will not help me in refunding me. I don't understand how they keep clients if they cannot keep them happy...
