If you deny them, you are allowed, by law, to show them their credit report. There is no guidance I have seen as to whether this means oral, written, or parts of the report or the whole thing.
A separate question is, do you want to.
And it should be noted, you don't have to. The CBA is the best equipped to discuss it with them. But it can be easier to show a person their report and tell them what you're looking at, so it can be corrected.
