I would not accept this solution if I was in your position.
After a big impact like that, who will ensure me that everything will be perfectly aligned afterwards?
It is like you buy a new car and the service store crash it hard and then they say don't worry, we will change the outside so it will become new.. What about the chassis, the keyboard part and all that staff?
I would not trust this store anymore and I would insist on them to bring me a new one, but well that's just me, the weird customer.
I hope you get it back in good working condition soon at least.
