Unity Health not providing pre-authorisation

As client of stratum associated with UNITY HEALTH MEDICAL, I am utterly unimpressed with Unity Health as I have been calling the Pre-authorisation number since last week Tuesday, 23 January 2024 to get an Authorisation Number for my son to go see a Specialist. I was told that I will be called back within 48 hours. Till today, 29 January 2024 I have called twice, being placed on hold for more than 30 minutes at a time, did 3 mobile app requests and 1 online (website) request, and still have had no feedback for my son to go to the Doctor on Wednesday 31 Jan 2024. I will never recommend anyone to waste their money with this health insurance. They have now implemented that you also must get a pre-authorisation to go see a GP, imagine that you might be half dead before they give your authorisation to go see your GP.
