Misplaced track bars (wrong track bars)

Hello, and once again unsuspecting abysses open to me. I had my girlfriend fetch the car from the workshop today. They also looked over it again.The master there fell out of all clouds, allegedly in my car wrong and also wrongly built cross handlebars in front.He only meant that at an OPEL workshop the car would not have been issued!!!???? Does such a thing work at all? Estimate approx. 400 – 600€! e drives me crazy ….. PS. These are the built-in (when buying already in) no idea who screwed up that when.
