Continued detoriating of Sizwe Hosmed services

I refer to my previous reviews on 20 and 26 April 2022. The refund for the service rendered on 16 Feb. 2022 was made at last after nearly 3 months. However, only about a third of the amount was refunded. Preauthorisation is suddenly required for the same follow-up consultation/checkup which I have had on a regularly basis during the past 4 years after a mouth cancer operation. I enquired about the situation, but as usual still waiting for a response. And guess what? I just received an email from them, asking me to submit the claim again. This is a respond to my mail sent on 17 March 2022. It is absolutely beyond me that a good medical Scheme like Hosmed has deteriorated in a just couple of months after amalgamated with Sizwe. Is it new staff, simply a change in attitude, new management/directors?
