No communication about products within DISCOVERY HEALTH

I was informed via Pathways on Discovery Health to purchase a new blood pressure monitor and download an app and start tracking my blood pressure. Very long story short, the app was not working properly and I could not claim directly from Discovery it was immediately rejected on the app. I paid for the monitor out of my own pocket and submitted the claim with an invoice from Brandmed - which was once again rejected by Discovery as apparently the invoice did not have the correct procedure code. I have been trying to sort this out for 2 weeks without any feedback, and the call centry of Discovery Health is not aware of the collaboration between Brandmed and Discovery and Ntombi that I spoke to brings Clicks into the story, which I am not interested in. Can SOMEONE please help me.
