is this the most difficult vehicle to ever bleed the brakes on?

took my works van in to ats (company has account) for new discs and pads on friday morning.

im still to get it back. they said that they had problems bleeding the brakes. new master cylinder needed...

was sposed to be ready tuesday and its not. some crap about a brake line had cracked and was blocking the fluid passing.. i didnt know know that was possible as when thy crack, they leak!

anyway, a guy has socalled spent 2 days trying to bleed them and still not managed it...

i think they are full of shit tbh, but are they missing something? other than braincells?
