Scheme paid codes - Then declined PMB as the codes that was paid is not on the authorization

Practice Number - *** Membership Number - *** Date of Service - 23/05/2023 - 24/05/2023

We send the account for PMB review, after following up on the PMB review request the scheme requested that we sending reports for the PMB review to proof the PMB.

We send all reports. When following up today the 17/10/2023 on the account the agent is stating that the PMB committee declined the PMB as the RPL code 5755 was never on the auth. My question to the agent was then why was code 5755 paid at scheme rates the agent just keep on saying that is what her screen is saying and we must update our auth.

Can someone please urgently look into this matter as how did the scheme paid the code originally then if it was not loaded on the auth.
