I agree with
@Paul Cott above.
While the creditor can't enforce (in the legal sense) payment of the historic debt (that was dealt with by the bankruptcy),
that creditor can certainly refuse to do any new and/or further business with you.
Last time I heard of a case like this,
the board was trying to sack the discharged bankrupt
so that the intended supplier would then go on to supply them.
As in "We're happy to supply you, but not if it involves working with
that guy."
