Unsatisfactory service

I booked a vehicle on Tuesday, tried to pick it up this morning. However, Bank transfers between 2 countries resulted in a 1 day delay. This morning, a very rude assistant @ Avis, Gautrain in Sandton, informs me the car is not available, she will contact me. Been waiting for almost 2 hours now. They chase customers away without offering the bare normal service. Was going to pay R40k for a 3 months rental....Mxm
