Discovery - Call center prompts are useless and cant get to update my information

I have been trying for two weeks to update my information as Discovery have the incorrect information, It still has not been done. It's a joke to try to talk to someone from the call center as all you get is the option to press and you don't know which option to select, it is like a puzzle. I don't know what more to do to update my medical aid details... it is shocking.
