I'm Sorry? What an odd response.
I didn't expect taking it in on the 21st August would be so much of an issue in the first place. The reason this dealer was used is because its where the car was bought from (although they have now been taken over) and is in walking distance of my wife's office. The closest one other than that is 20+ miles away. Would you have done things differently?
Hindsight (a wonderful thing) we would have had it in a week earlier at least but as I say, we didn't expect to have an issue that would take so long to resolve. So do you book in with your local dealer, the location you bought the car from and is walkable and have it in 10 days before the expiration of the warranty or do you have it with another dealer who is a significant distance away (they may offer pickup and collect but don't know and its not a thing we needed to know).
Likewise, when this issue was raised on Wednesday post service, they stated they didn't have a part in stock so we stated we would take it to the other (20+ miles away) dealer as they did have a stock part. However, the place we dealt with stated we wouldn't be able to as they had submitted the warranty claim and therefore the other dealer wouldn't be able to do so. Again, hindsight, but that wasn't an honest response as they hadn't submitted the claim at that time and had I known it would take them 3 days to submit the claim we'd have just taken it to the other dealer to sort out hopefully a lot quicker.
But thanks for your comment....
