Bonitas not resolving claims accordingly

On 14 May 2021 I called Bonitas. I had a claim for a new wheelchair. The person at help desk, Angelique Pretorius, assured me she will get back to me. According to herself the scheme rules changed for the plan I'm on end of 2020 and they now only pay for wheelchair claims out of my savings account. I told her that thiswas done unprofesional because I was not aware and this was not communicate thru to me properly for if I knew I would have go to a better plan to sooth my needs to cover a wheelchair. She send me an email on the 21st of May, stating that Bonitas will pay R9 900 for my wheelchair from PMB. My wheelchair cost over R23 000. I forward the mail to CE mobility the service provider for the wheelchair. Th medical aid logged a claim and only paid over R900. I am wheelchair bound and need a new wheelchair urgently. I queried the claim. Today is the 13th of July and my problem is still not resolved. I called the help desk and all they can tell me is that they will come back to me before Friday end of day. I told the agent that I need the wheelchair and want a solution today.. Because this is going on for 2 months already. He said hold on and then put the phone down on my ears. This is unexcepteble. I never skipped a payment and I contribute almost R60000 per annum.
