No valid reason for rejection of authorisation

Recently found out that I’m expecting and I activated my maternity benefits, I later called to confirm if they’re activated and what benefits I get as this is not something you just get you need to activate it before getting the information. My gynecologist then requested for NIP tests to be done, this is my first pregnancy and I’ve over the age of 30 so there are some risks that we just need to clear. She motivated why I needed these text and discovery declined saying it’s not sufficient motivation. Why do we pay for things when we will later be told that it won’t be done? What the use of actually going through all the hassle? Called the call centre and the consultant also was give me the response that was email to me not explaining what I’m asking. I’m so disappointed with their treatment as a first time mom this is the last thing I need and this stress is not what I need
