Never ever Tempest again

From the moment I walked in the door at Tempest Car hire in Cape Town airport, until today (three and a half weeks later) I have had only a bad experience with this company. Starting when I arrived: There was no queue, but none of the 5 or 6 agents sitting at their desks wanted to help me. Instead, they did their best to ignore that a new customer is there. I went to one agent and he said "no go to that guy".. No greeting, nothing friendly... What were they all so busy with, with no other customers in the house? The process of getting the car was a pain compared to all other rental car companies I've used. Why do I have to provide my address and contact details AGAIN if I have already done that when I made the initial online booking?? After I received the car I noticed that the fuel tank is NOT full!!?? The rental clearly states it is from full to full, so why am I getting a partly filled tank? Someone did not do their job. I went back to the guy and told him about this. He said the best way to handle this now is that I fill up the tank myself and keep the receipt for when we return so that it can be refunded. The alternative is that I get a much smaller car - which is not an option - we specifically needed a large car for this trip! So, up to today, I have not yet received the refund for this fuel which was a mistake on their part. Also no apologies for the inconvenience or anything. So I paid for someone else's fuel and cannot get my money back. The car itself did not have a seatbelt on the left back seat (which is required by law). The biggest problem occurred however when we returned the car. There was just one lady there to process returning cars, and she had way too many cars to handle (and was extremely rude to all returning customers, because she is so overloaded). Other staff were sitting in the office or trying to ignore customers. In addition to this, there were NO trollies to take the heavy load of baggage from the FAR side of Car Rental returns to the airport terminal. I notified the staff that there are no trollies anywhere, but they just shrugged it off and said it is ACSA who provides the trollies... I am SORRY but YOU are the guys who provide the service to customers here, so you have to make sure there are trollies for YOUR customers. To blame ACSA is the lamest unprofessional thing you can do. We had to run up and down that whole airport parking area to try and find a trolley - with the result that we went from being on time for our flight to very very nearly missing it, just because of the utter incompetence of Tempest staff! I am pretty sure that I will just get a canned response on this platform but hopefully, I will at least get my money back that you owe me because of your mistake. After that, I hope this company shuts its door for business soon, because to treat paying customers like this is an absolute disgrace!
