No emergency assistance

We arranged a car for Monday morning early to go to ORTambo. They asked that we fetch the car on Saturday as they were too busy to drop the car off for us. On Saturday we realised that they close at 12:00 on Saturday and that we had missed the car pickup. Firstly, nobody gave us a call to ask if we would still be fetching the car. Secondly , when we got to Avis offices - we realised they were closed and phoned the national emergency number. The lady was not helpful at all, just continuously saying that nothing could be done because they are closed. We asked if they didn’t have a local number for someone to assist us , but she kept on saying no , they closed.
