Can someone give me update on my query

Ref No: *** I called discovery on the 3 May 2022 to report claim that a certain doctor billed on my account. I explained that the claim is invalid and therefore should be reversed. The consultant promised to forward my query to a relevant department. Nothing has been done, the claim was even paid after i reported it to be not valid. It has taken discovery more than a month and few follow up on my side to request for update. No update and nothing seem to be done about my issue. I even log a complained, nothing done. May you please reverse the claim so that i can go consult with my doctor and get a script for my chronic medicine.
