Bus not roadworthy

We have been waiting for the bus 800 since 18:00, the bus has been held by the traffic department due to faulty breaks. The bus sent an sms only 10mins ago (8pm) to notify us of the operational delay. The bus we are waiting for will arrive at 2am to transport us to Pretoria. We asked for a refund as this is their own fault and they told us we'd get the refund between 14 - 21 days. I need my money to take other transport means. They don't even update us.
