Discovery health not wanting to refund me vitality money

In 2021 I took medical aid with discovery the broker advised and sold vitality and I explained that it wasn't going to help me from the list of the things they said I was going to benefit from. So she said they will give it to me for 3 months if I don't need it they will discontinue... I told her I won't need it after those months. So I stayed under impression that I didn't have vitality up until last year 2023 early in the year. I asked that they cancel it and refund me. Ever since then I've been calling emailing connecting through all their mediums in vain. The fist call I made I requested for the recording which I was promised by the broker because I was told the broker was responsible for my case. She gave me excuses saying her senior was going to help her get the recording. I need my money which was deducted for all those months from 2021 to 2023
