Discovery medical aid bully tactics. Unfortunately I couldn't select a 0 star.

I have been retired for the past 10 years and have been a member of Discovery medical aid for the past 30 years. When retiring my company gave me the option to receive monthly contributions of 2/3 company and 1/3 for my account. This however has a capping of R2743. On 1 June 2020 I requested to change from Classic Saver which included MSA to Coastal core scheme which is hospital only cover. This resulted in a significant reduction in contributions by 50%. Discovery did not adjust the monthly contributions from my employer which should have occurred. This resulted in my contributions being less than the 1/3. On 16 May 2022 Discovery advised that my company had performed an audit and I had been over-paid in company contributions. Discovery in turn repaid the total amount to my old company. Discovery advised that they had made a mistake and that the under payment would be recovered from me over the next 18 months at R334 and that my monthly contributions would be adjusted as from 1 June 2022.I responded to the email by their Billing section only to be answered a week later by a person that has absolutely no customer relations or respect on dealing with members. As of 1 June the debit was processed but the additional amount was not included in the contribution. On 6 June 2022 I received an SMS advising that my Medical cover was temporarily suspended. An email followed advising that the full amount of R6048 was due within 14 days. Failure to comply would result in my medical cover being canceled. I sent two emails to the Principal officer at Discovery and have had no response. What I really have realized is that Discovey really do not care of their members, this is what happens when you become the biggest. You forget about being the best but it made me realize that Discovey only treat you as a number
