No service!!

I decided to try this service for the first time today. I booked my first vehicle at 04:31 today, the app sent a confirmation that a mr Mncedisi in a Nissan Almere would be arriving in 15 minutes . 10 minutes later I received a message that the driver had cancelled the trip. I still had time so I booked again , again the app acknowledged the booking and confirmed again that mr Mncedisi in a Nissan Almere would make the pick up in 15 minutes ... Ten minutes later a cancellation notice is received stating the driver had once again cancelled the trip. It was now too late to book a 3rd time so I must use my own vehicle and leave it at the airport for a week incurring unecassary parking costs. A poor first time experience and I would certainly caution anyone using this service ..... Goed Koop is duur koop....very disappointed !
