high repairs on my car

I have been filling up petrol at this service station for almost two years. It is on the road to my home so is very convenient to stop there and fill up. For the last 3 months my car started doing funny things like huffing and puffing after filling up there and then on the 3rd of april my car totally gave in. I took it to a qualified mechanic for my car. I am driving a ford Mondeo. Now suddenly everything is just goint the opposite way. He stripped the car en eventually got the problem that have been causing all the problems. My petrol is full of water This water blocked the petrol filter my injectors rusted things where petrol were petrol is suppose the flow and all is costing me now a lot of money. My car is been standing still and still need work and replacing of things because of this water in the petrol. This Engen garage has been closed now for almost two weeks and everything is being built from scratch again. From the heavy rains the tanks filtered water through into the petrol that has been poured in The cost on my car is already R9000 and still not driving.
