Petrol pumped into Diesel vehicle

On Saturday 23/01/2016 just before 5pm, I went to fill diesel into my vehicle. I requested from the attendant to fill R100 diesel into my bakkie and I proceeded to the Garage shop. Instead of filling diesel the attendant filled petrol. After leaving the garage I proceeded to Anstey's beach when i started noticing my bakkie loosing power and back firing. I got stuck on Bluff road and my vehicle refused to start. I contacted the garage and managed to get the owner Gregory's number. Upon contacting him the owner, he was very arrogant and was refusing to be of assistance, after arguing with him he sent a tow truck to tow the vehicle. I had to arrange alternative transport for my family to go home. I was towed to back to the garage, the petrol was not drained out properly. The starter motor in my vehicle is burnt out and needs to be kick started, I am now put in an inconvenient situation as my vehicle is used as my transport to work.<br> Contact Sheldon urgently as I need this resolved.
