Premium

I registered my aunt's daughter for medical aid. The premium was supposed to go out today but it hasn't. I tried to register a profile for her on the app. When I enter her email address or phone number, it says it's not the details on file. When I enter mine, which I used to sign her up, it says email and phone number already linked to another profile.

I tried to search the help button, but it's only phone numbers. I'm out of the country traveling overseas, so I obviously cannot call. There is no email address to contact, hence me logging a complaint here. Can someone contact me urgently to make sure that the premium goes off and help me with registering her profile on the app.
