Affinity Health Client Services Cause a Clients Financial Loss

I am required to go for yearly G-Scopes after being diagnosed with Barrett's oesophagus, I go to a Surgeon for my G-Scope as her knows my history and initially diagnosed me and he does the G-Scope in his rooms (so no need to book into a theater). Knowing that Affinity Health always requires authorization I first emailed the team to inquire as to how I should approach this after which I was called by a support staff member, I asked her if the procedure would be covered and she said yes it would be covered under my day to day, I then asked her if she was sure that it would be fully covered and she said yes, she also mentioned that if it was to expensive I could be booked into hospital for it, at which I was confused as she just said that I would be covered for the day procedure. Long story short I am now out of pocket by R3 570.59 (G-Scope and Biopsy) due to the negligence of the support staff.
