Stranded at the air port

I bought a 3 day car care voucher through Hyperli at Air-o-Car. I requested the company to take my vehicle for a service whilst I am gone since I have arranged the service and gave them all the contact details and address together with my flight schedule.Air-o-Car agreed, my vehicle was collected and off we went for our week-end. When we landed on Sunday at 13:40, we went to the arranged meeting place only to not find my vehicle. We waited 5 minutes and I then gave them a call. I was told my vehicle has just left and should be at the meeting point within 10 minutes.5 Minutes I received a call back saying that they have made a mistake, my vehicle was not on its way but was never collected from the service center and since it was Sunday it can not be collected. Needless to say that this caused a lot of problems, as my wife and I both had to work the Monday and we stay in Ellisras about 350 km`s from OR Tambo. After several phone calls all we got from Air-o-Car was a vehicle for the night, no accommodation or any other assistance. My wife and I both had too take an extra 2 days leave, for the Saturday and Sunday, as it is a policy of our company that if you take leave the Friday and the Monday the week-end must be included. The Monday was black Monday and we were trapped in traffic on the N1 going north for 3 hours. We really tried to get some assistance for Air-O-CAR but they were very snotty and not willing to accept responsibility for getting us stranded, paying for accommodation, dinner, breakfast, stuck in traffic and missing our grand daughters price giving at her school due to getting to Ellisras after 6 PM.
