RENAULT KERAX 420 BOARD 420

Hello,

my consultation goes from the Curate Board of a Renault 420, the reason that it has not left the workshop this week, good I tell you, order the board and the next day I had it, when I took it to the workshop without problem but today they tell me that they do not place it because the board that takes is complete They were wrong to sell me the Board or the mechanic is too long and left lying.
P.S. When I bought the Board they took the reference number from the chassis number.
Greetings
thanks
