Poor service delivery

Took my car for service at Meyers, King William's Town just after 8 am, this after waiting since Monday to get a qoute..... At around 15:38, they just called me to tell me nothing was done on my car as they picked up that the coolant had no water. When I asked why the car was let unattended since then,I'm told I didn't drop the car at 7:30... like seriously?? Talk about poor service delivery... basically I lost a days income as I had to postpone a case in lieu of service
