After it's fixed you won't even be able to tell, I mean it's a door, no structure or severe damage, they fixed it, you had a rental....document it, and if issues arise down the road which more than likely will not you have proof that area was damaged.
People saying they would take the car back.....get a life. I can just imagine what people like you are to deal with in general. That is seriously although annoying minimal damage, that shouldn't have happened.....which you won't and anyone looking at your car will know happened. Bottom line is it got fixed, sure they could went about communication better, but to many people overreact to little things like this when there is more important things in life to put as much energy into, let alone one that got rectified.
