Can't get pre auth from Momentum - Poor Service

Going for an MRI scan today. I tried seeking pre authorisation through the app on Friday. On Monday I sent a follow up email, and another two on Tuesday. I got one reply asking for an ID (which I responded to) and nothing else.

Too often now I need to resort to this site in order to push Momentum into performing their basic functions, but if Hello Peter is their preferred means of communication the so be it.
