Missed Flight due to Incompetence

I made my booking with OR Tambo Parking 21 March for 22 March 2019 and after receiving booking confirmation, I still asked the operator whether someone would be available at 04:45am as my flight was leaving at 06:05, she confirmed there would be.

15 minutes prior to arriving at the airport I attempted to call ********** as per the company SMS. It went directly to voicemail. I then attempted to call ********** as per the company SMS. The number just rang. I then attempted the emergency only number ********** , but also received no reply. In total I placed a total of 18 calls and on the 19th call, someone finally answered. This was already at 05:15. I was informed a driver would be dispatched. At 05:30, still no driver had arrived. I called again and was told the driver was pulling into the terminal B departures. I handed the car over and ran into check-in. Upon arriving at the desk I was told I was too late to book in my luggage and as a result had to forfeit my flight.

I had to book myself and my son onto the next outgoing flight at 08:10 at the whopping cost of R2046.00 extra.

I was sent the supervisor's contact number, which also only rang and at 07:18, my SMS to him went unanswered. Eventually on 25 March, I received a reply to my written complaint, informing me that the manager was out of the country till 2 April and he would then respond. They admitted there was a problem with their server and calls coming in. I again requested a resolution to the situation but to date, almost a month later, no-one has bothered responding in any constructive manner.
