Urgent

So I had taken out this medical aid for my dad in April and on the certification my dad's benefit date was on the 01.04.2025 which I have proof off, all of a sudden my dad falls sick and I had to admit him in hospital not knowing what's wrong with him and why his fallen sick because all these years my dad was not sick he was 💯 fine, then on the 08.04.2025 he got geey bad he couldn't breath or anything, so now because of the medical aid certification which I have solid proof of is stating benefit date starting on the 01.04.2025, I'm under the impression that my dad can and will be admitted, so the next day the hospital calls me and tells me that the medical aid declined the auth became he has a 3 months waiting period and then I told them and emailed them the certification and they said the underwriting made a mistake, so I told them how is it my problem, then after that I took my dad out of hospital and from the 08.04.2025 till today my dad's health has gotten beyond critical and so happen I admitted him last week Thursday which was 10.05.2025 and they have change his certification to the pmb payable within the waiting period, bow my dad has got authorization and my dad is very bad because of they mistake, now that the doctors want to send him for a biopsy they are declining it because all of a sudden my dad is very sick, and this is not right because according to the government the law states that anyone whom is very serious no matter when they have fallen sick and they have pmb the medical aid has to admit and do all the treatment no matter what
