Fedhealth took my money

I joined Fedhealth in June 1 2025, unfortunately my previous medical aid kept on deducting the monthly contributions, as a result that I was owing 2 contribution at Fedhealth, then Fedhealth terminated my membership, I wrote email asking them to reinstate my membership, they refused, mind you they have my money with them. R2990, to me that is *******. Since they don't want to reinstate my membership they must bring back my money. Because there were no claim was done on Fedhealth membership.
