Sad customer

My Hyundai ix35 went in with a fixed windscreen and came out with a cracked windscreen. I was told if there are chips (that means every car) then they are allowed to break the windscreen on their hoist which twists the car. I am so sad, I bought my car there and it has had every service for 10 years there and this is the response when they know they actually broke it!! I liked going there and now I have to go somewhere else. Anyway, next step is the ombudsman.
