Engen Garage - Not sorting out issue

Disgraced at Engen SA for keeping Engen Lotus Garage in Umhlatuzana durban under its wing. Incorrect fuel filled in vehicle and having issues from its Owner, Nishal in sorting my vehicle out. The clean up has been done but the vehicle is misfiring since the incident. Nishal shows no intention to sort this matter out and a horrible experience from this place. There is constant issues with the owner and the garage sorting this out. This garage employs trainees to fill your vehicle and then cannot sort out their liability once they fill incorrect fuel. My vehicle cannot be driven in this condition. I have asked for vehicle hire but still no response from this garage. Share far and wide! Do not fill at this Engen Garage, Engen SA need to come to the party and pull the rights for this owner to operate the garage under the engen brand. This is a disgrace to the Engen Group.
