KÖLN petrol instead of diesel in the pump

Hey!! I was filling in at a petrol station in Cologne on 15.5.2012. I definitely filled in diesel – on the receipt was also DIESEL billed. After about 80 km my car simply went out, I had to roll it on the side stripes and fetch the ADAC. It came out that I had petrol in the tank. So towing, pumping, hoses exchange = 1,400 € in costs. Who also filled it or who did similar things happen during this period?
