My 2p - sometimes people make mistakes, If they've generally been good about the care of your car then I'd say the continued care is worth it. My friendly mechs have messed up a few times with my car, but on the other hand they've helped me out of a jam a fair few times (and also tried to put things right sometimes).

 

Swings and round-a-bouts.  I hope this doesn't soil your friendship and things get sorted amicably

I agree. There was no malicious intent and it appears they were simply acting in good faith based on their workshop manual. Perhaps the workshop manual need to look at their instructions (if Skoda confirm it is 4 yrs) but this can’t be hung around the neck of the garage IMO.
