Hollard and IUA are not honest

I'm not happy I'm sad as I was sick from December 2024, which led to my admission on 30 December 2024, due to COVID, then one of my kids got infected as well, he then got admitted on 1 January 2025, the. Last week on 16 January I sent claims to IUA, it was a fight as always, they couldn't even register the claims, after a long fight and stress they did a right thing. Now they sent me an email saying that my claim is declined because Hollard said so. How can my claim get declined when I'm the one who got infected earlier, now IUA is pointing Hollard, when I call Hollard they point IUA. These two companies are playing with people, making empty promises to people. My ID number is ***. My cellphone is ***. I'm very sad and disappointed at such a big company like Hollard, I was not ready for this. The only paid claim was for my son, mine is declined without a reason, I'm talking about an honest claim.
