Returning Superseded Numbers

So I follow my PDC's instructions on returning superseded parts which are this:
4) When returning Superseded Parts to the PDC: Once you receive a Material Return tag for a part that has a superseded part number, you will need to place a white label next to the return tag you place on the part package / container. Be sure to write “SUPERSESSION” on the white label. Please do not cover the old part number with the white label.
I get a grille returned to me from my PDC where someone scribbled on my return name "not a suppersession".
I double check in part information and it defnitely is a valid supersession.
I call the MR supervisor at the PDC he tries convincing me that the only superseded parts that can be returned are RIM parts! I told him I returned 2 or 3 other superseded #'s on that same return and received credit for them and he says I shouldn't have.
Anybody else ever have this issue?
