Bad service from Barons Woodmead

On 23 March 2020 we took our car in for its 60 000km service. When we got home the car's idling was very high and there was a strange sound coming from the engine. We phoned Simone and arranged for the car to be fixed the next day. On 24 March we took the car back and they told us that it was a pipe that came loose. They fixed it and when we came home we had the same problem. We took the car back and the workshop manager told us that it was a pipe that was broken due to the car being in a previous accident. They have to order the part but it will be for our account. After further investigation it was realised that their mechanic actually broke the pipe an d glued it with quick bond. We will go back after the lockdown and get the car fixed on Barons' account. We drove to Lydenburg with the car and came back and had no problems. Why now after the service the pipe all of a sudden broke.
