Reward points

I have been unable to access my Rewards points since May 2023. Despite my visits to the Old Mutual branch at Clearwater mall in Johannesburg,the problem has not been addressed by Old Mutual in Cape town. The problem-Error landing page-keeps popping up on the Rewards screen when we want to access my points for usage. Head office in Cape town keeps informing me that the problem will be addressed within 48 hours,but they never get back to me or the Clearwater mall branch. I need my reward points to be backdated to December 2022
