This is so frustrating and just shouldn’t be happening. I can completely relate to this though as it’s identical to what happened with me, with Marshalls of Reading confirming they had 04S for me and then fitting 03S. Just to rub salt in the wound, besides chipping the paintwork, I am booked in for replacement of the replacements next week and they confirm that they have 04S for me but prior to 9th November. Despite knowing that two weeks ago they still haven’t sent those back and reordered, so they will now have a vacant slot in their workshop next week that isn’t earning them anything. Despite knowing that they have the wrong dated bellows it seems that they have told Adrian at VWCS only 2 days ago that they have the part to remedy my van next week. Something so simple to understand and still they keep conspiring to frustrate us. No excuse for the poor workmanship that you have experienced, problem is i sense a lot of them seem to view it as “just a commercial vehicle” rather than somebodies pride and joy
