Hello Doctor / Momentum - shocking service

I have been unable to access their service today, despite the fact that I am a paying Momentum Health client who should receive the service for free.

Hello Doctor app - receive a blank screen when opening.

Hello Doctor website - no option to request a call back. The chat function actually takes you to Health4Me.

Momentum app - the function to Talk to a Doctor is not working.

Momentum website - the function to Talk to a Doctor is not working.

Hello Doctor USSD code - also does not work, whether you try the Health4Me number or the Momentum Health number.

I was lucky enough to get through to them yesterday via my partner's app (which has since stopped working), but the doctor was difficult to hear, kept interrupting me, didn't provide me with a diagnosis or tell me what she would prescribe. She hung up before our conversation was done. She called back later because she did not know how to request for me to submit payment for the service (there is a fee if you want a script or a sick note). She clearly had no idea how the system worked. She referred me to Momentum, who referred me back to Hello Doctor, and it has been a total mess trying to resolve this. In the meantime I can't get the medicine I need and don't have the sick note for when I return to work.
