@Kezo is correct
I think the only thing I’d actually miss without the Advanced pack would be the HUD (Heads Up Display) I find it very useful.
The Canton system really isn’t that much better than the standard sound system, certainly not worth the price.
Heated rear seats and rear cabin climate control? do you really need them/it? mine are never used, in fact I thnk I’ve only used the drivers seat once!.
Heated windscreen, pointless on a car you can pre-heat, you get the whole car heated and the ice melts off the screen.
Get you £2035 back and also demand some sort of compensation/goodwill gesture if you accept the car.
Oh yes, I forgot about the crystal face grille, almost the most pointless “upgrade” ever! Absolutely no benefit or improvement to the car, just looks nice in the dark when you open or lock the car!.
If you need the heated rear seats for your daughter then by all means make them find you a car with the correct spec you ordered, Skoda have a car locator on their website, there may be one in the country already that hasn’t been allocated.

Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
