Damage to vehicle headlight when serviced

We had our Ecosport serviced on the 23rd of December 2025. Video footage proved the headlights working when booking the vehicle in for service. After receiving the vehicle back the right hand front headlight was blown and the cover of the light had a melted spot on it and a crack. We took the car back and reported this to the workshop manager. He told us it's nothing they did as they switched off the headlights when booking the car in and although connecting a diagnostic computer to the car was detailed on the invoice it was never done and he has limited video coverage and none to verify our claims and conclude that this damage is for our pockets and all he can do is to get a new light that we have to pay for and can only assist by having it fitted for free. We will definitely not be using Ford service centre Witbank in future.
