GOLF RESORTS - GET IT WRONG AGAIN

Okay so GRC have an annual levy that is payable each year approx 14k, thsi levy is payable in full amount or in installments. My levy was paid before 1/3/2022 and GRC still insist on showing on my credit report that the account is 2 months in arrears, this after I have received a statement showing my account is in good standing. When asked to remove the incorrect info from the credit bureau as it affects my credit score - deaf ears - no response. These remarks have now affected my application for vehicle finance, how do I get recourse - any one out there keen to challenge GRC on a legal level, as I am sure I cannot be the only person who is gatvol of this company. We ask to speak to senior managers, we are told none are available - BS, BS, N\BS - I do not recommend anyone in their right mind purchase GRC membership,. And when you try to sell they tell they cant help you, yet they continue to sell NEW MEMBERSHIPS and are oversubscribed as holidays are never available and the few who do manage to get them are lucky its like seeing a one legged unicorn - how can these companies be allowed to damage your credit score without recourse?
