don't worry. u have to get your letter of refusal in which the reasons backing this decision must be laid down according to the canadian immigration law. the intermediary agency has no any right not to disclose the information contained in this letter to you, althought u have concluded a mandatory contract with him. if there exist some clauses in the contract which restrain your information rights, these clauses will be deemed as unwritten and invalid according to la chartre de droits et de libertés des personnes. if u are a candidate immigrant of quebec, their acts are forbidden by quebec civil code.
anyway, this refusal decision is appellate, but i guess there must exist a certain periode of expiration of your appellate right. if u supass it, this decision will become definitive and has force de la chose jugée.
your case is irregular, for most of such kind positive decisions are due to the allegations relative to the authehtification of immigration files developped by canadian embassy, but anyway, these allegations are only hypothesis.
bonne continuation et bonne chance.
