Discovery health don't know how to add a member and website is malfunctioning.

Good Morning

I have been trying to add a member to my Discovery medical aid and have been sent from pillar to post. It seems no one knows how to add a member to an existing medical aid. I have tried since last week. My phone call gets answered and transferred but no one answers at the Business unit. My question is, is there no one at Discovery that knows how to add a member? The discovery.co.za website has bugs and you cannot submit a complaint. I tried adding a member online but the discovery website bombs out.

Seems like discovery health has major problems.
