Left next to road due to lack of service from Europ Assist

My insurance, Santam, offers a 'drive me home' service through Europ Assistance. We booked this service two weeks in advance for a trip home on 1 Jan. On 18:00 on the 31st, we were informed that they had taken too many bookings and did not have sufficient drivers available. Although we had made a reservation for 1am, we could only be collected at 1:30am. Considering we had no choice, and had already arrived at the venue for a function, we agreed. We were left at the pickup point, next to the road outside a closed parking lot until 2: 40am that morning. I felt absolutely unsafe and exposed, due to the lack of service from Europ Assistance. They do not have the infrastructure to offer the services promised to insurance companies, and I would not recommend or trust any of their services to anyone. They do not have the necessary resources and will leave you stuck next to the road for hours.
