Left alone without car hire or uber to get to work

I was having a damage at my car that needed repair. I dropped the car at the garage provided by discovery. It was also confirmed that Avis will drop a car for me there by discovery. On arrival there was no car but the garage staff could drop me off at work. After calling Avis they promised to deliver a car to my work at 15:00. No car was delivered till 16 and their driver was not reachable. I decided to uber home as it was my wife's birthday party and I could not wait further. I contacted Discovery and asked to activate uber benefits as means for transportation and cancel Avis. This was not done by discovery. As I was travelling for work I left it and went to pick up my car on arrival just to discover the paintwork was done incorrect by the discovery garage and I had to reject the car. No having no means of transportation I called discovery again to activate Iber benefits. They did not believe me that I had no Avis car and did not activate it. They promised me to get back to me but did not call back until they closed. No I have to get to work tomorrow and have no means of transportation. This is really bad service from the claim assistants.
