Pathetic service

Hi Recently i took my vehicle to Motolek Stikland to look at my one headlight being dull and the aircon not working properly. After the vehicle being there for the day, they phoned me to come and collect the vehicle as they were not able to fix the vehicle. When i got to the vehicle, i was charged R630.00 for a diagnostic on the vehicle, but they never told me nothing is working on my vehicle anymore. I had no lights, the lights on the dashboard were flashing like a christmas tree. The vehicle was worse off after being there than before. This is the worst service ever.
