Warranty extension Macan GTS

[Milnsey]

My wife’s Macan has undergone the 111 point check for warranty extension. All fine.
However the opc also carried out a complimentary wheel alignment check, as they always do.
Apparently the alignment is slightly out and they want another 150 quid to realign the geometry before they issue the warranty.
Alignment was only done 6000 miles ago when we had new tyres fitted, no sign of uneven wear on tyres.
Am I being taken for a ride? Why won’t they let me just take out the extended warranty without the realignment?

After a few increasingly terse phone calls they agreed to realign the geometry free of charge
