Pathetic service

The most pathetic workshop i have ever been to. I got there at 10h53am for battery replacement. 3 hours later, after watching them try 5 different batteries then my car was left unattended while Johannes decided to attend to a different car. I have already paid yet i am not receiving any service. How long does it take to change a battery? I will never set foot here, let alone recommend it to anyone. Yoh what a waste
