Watery fuel and stinking ****** attitude

Went into the garage and poured fuel on my new Toyota bakkie (+-17500 km). It was just below quarter tank. Asked them to fill it up. Correct fuel was poured in according to the pump labels. After filling up the car didn't want to start and was jerking. Spoke to the manager on duty and we agreed to call a mechanic to drain the fuel and re-fill the tank so as to eliminate the possibility of water in the fuel. This was done and the drained fuel contained water and an unknown substance. The tank was re-fueled and the car started well and hasn't given me problems till now. Problem started when the manager on duty today decided to call me and tell me that it's not their fuel that has a problem and he doesn't give a \****"what the other manager that was on duty on the day of the incident said. Have sent a complaint to Chevron SA. The car was fine all along until I poured that fuel and to have someone call and use foul language on my phone after having resolved the issue with the manager that was on duty is just wrong. The man was rude. I think he said his name is Mark"
