Dont be tempted by Tempest lower prices

As I was flying Kulula and being a Discovery Vitality member I thought I would use the Car hire option which attracted a discount I booked a Ford Fiesta through Tempest the company on the Kulula site. I duly arrived at OR Thambo Airport on 20 December from Cape Town and went to the Tempest desk it was empty then reading a small sign stating that Tempest customers must collect vehicles at Europecar. I duly went to Europecar and stood in the queue for 45 minutes waiting. There were 2 people on the counters and 14 people waiting for vehicles after this considerable time i received my vehicle not the ford fiesta but a Renault but thats beside the point. There was nobody there to go through the vehicle to check everything was in order to not chip marks on the bodywork and windscreen. I returned the vehicle on the 23rd and filled up the tank before returning it back to Europecar on arrival there was one attendant and he was busy with some gentleman told me to give him the keys and go I showed him i had filled the car up so the only outstanding charge would be the toll fees. It is the 28th and the charge on my card of 8900 has still not been refunded when I called customer service they advised that it takes 10 working days to process the invoices so I can expect the refund on 8th January. Most companies put a hold on your facilty not physically charge your credit card I find it totally inefficient and wont be using Tempest/Europecar in the future
