Nap 250 back from service query (not sure I'm happy with the dealer)

hi all , I have just picked up my Nap 250 back from service from Salisbury , upon getting home and looking at the job sheet it appears that , 

A , I have had my full service.

B , parts used show a box and labels with all internal packaging.

i did NOT have the unit returned with any packaging at all , even though it appears this is paid for in with the cost of my service , I phoned the dealer and they said, as I didn't take it in to them in a box and they put it in a box to send it away ,it was returned by naim in a new box buy THEY (the dealership) have kept my box , this is an authorised dealer that I was told to take it to by Naim, there was no mention that I had to package it at all as this is an authorised dealer, I was of the understanding that this is all part of the dealerships service that they provide in return for the priveledge of being chosen as an authorised dealership .

the parts listed that I have not been given are as follows,,,,,,,,, 2 x end cap foam reference ,,,,,1 x inner wrap large carton reference ,,,,,1 x large carton printed reference ,,,,,,1 x label blank 73 x 174 white ,   1 x silica gel sachet.

does this seem right to any of you , surely as it is all listed on my job sheet and I have paid for it all shouldn't I have been given my amp back with these items? ,,,,what right has the dealer got to take any of this away from me , in fact what right does the dealer have to open the box that is being returned to me by Naim , they are just a middle man as a point of contact for collection and returns. Should I give Salisbury a call and express my concerns?
