Whoa that aint right, its quite simple really, the tailgate should sit flush with the tail lights, what do they find so difficult to understand about that? Or do they all own cars with wonky tailgates and bumpers making them think this is normal?
Cant believe you've had to wait that long through no fault of your own, sorry but seeing this kind of idiocy really pisses me off, cant imagine how it makes you feel after all this time.
Hope you get it sorted soon mate
