Hospital bills not paid between Medical aid and Mondia wellness 30301037584

I was on AECI medical aid, I went to Mondia wellness in Vereeniging. I was admitted on the beginning of 06 October 2025, Stayed there till 30 October 2025. The problem I have is that the hospital is claiming that the medical aid did not pay them, whereas the medical aid has sent me a statement showing that the hospital has been paid in full. This morning I had a call from Zelda Rathbone. I have forwarded her a proof of payment from medical aid side. It still looks like there is an issue. Please help.
