IUA refuse to pay claims

I have a policy with IUA which I took with Edgar's, last year November, on December they deducted money from my Absa bank, then the premium came back as they failed, then January 2024 again they didn't deducted money, then the policy cancelled, I called IUA to restart the policy, they did and they keep on doing the same thing, until I decided to give them Nedbank account details, they then restarted the policy in June 2024, in September my kids got admitted, now IUA is turning a blind eye, claimg that they sent the claim to Hollard, but when I call Hollard to find out, Hollard is disputing those allegations and told me that maybe IUA is using this strategy to avoid paying for my claims, I lodged a complain with IUA, but hey they are all colleagues, they are like family and I'm the outcast, I've never been disappointed and exploited like this.
