Bad Service

I went to Caltex in Wynberg Johannesburg today(01/08/2019). I asked one of the Petrol Attendance to pour water as my car needed water. As I was driving off there was a leak under the car and the car started to overheat. I drove back to the garage, only to discover that the lady that was assisting me actually poured petrol in the water pump. I spoke to manager who was not interested in helping with the issue. I must say his attitude was disgusting to say the least and very unprofessional. I'm very disappointed and angry as this has brought unnecessary expenses because of people's negligence.
