What a pathetic spineless medical aid that cannot answer simple questions

I sent a query to Discovery on February 26, and then again on March 1. Every time I get a nonsense response that Discovery will respond in 2 – 3 working days – What false *******! What a spineless amateur organisation! Previously: I had two eye lens replacements at the Busamed hospital by Dr Falletisch on 14 February and 21 February. I am a bit puzzled by some payments by Discovery (Classic Priority, No ***). The claims by Dr Falletisch, Dr Theron (Anaesthesiologist) and the hospital were paid almost completely by Discovery. However, there were preliminary tests done on December 8, 2023 and I only recently received a bill from a Dr Kriek (which I attach), who claimed that R 5016.50 is still outstanding. It is stated in the account that “We have paid up to the member’s chosen rate from the Medical Savings.” Why would I choose a rate which only pays a partial sum when the other payments were paid almost fully? The payment to the Dr Kriek practice amounted to only 39.5%. I would appreciate it if you could shed light on this matter.
