BMW Sheer Driving Pleasure Gone Wrong

Bought BMW F20 last year March and this year I took the car for it's first service at Lyndhurst Auto.A week before that I discovered that the air con wasn't working so I asked them to check and return they are telling me that the air condenser needs to replaced as it is damaged and it looks like it was hit by stone..The funny part is that MotorPlan doesn't cover it.Then I called the sales person whom I bought the car from and he return he told me that I'm not the first to report such problem to him.My advice to BMW SA they need to do follow up on this and if it means that they recall all the F20 model then they've to do that.For now can they just fix my car...Sheer Driving Pleasure I disagree.They don't know how to treat their customers and also meet their clients halfway.
