Hi got a 2021 scania r460 there was issue with the horse plug for the lights scania assist came out 3times and could not fix the problem because they had to no stock of the plug so I managed to get the part on my own and asked them to fit it and now they want to charge me a call out fee because it was a Sunday and they guys came out spoke to the workshop manager Jared who is arrogant and doesn't know how to speak guys when buying a truck really consider volvo
