Netcare Accounts department - No client service

Good day I visited Unitas Casualty on 24.12.2019 of which some accounts were not paid due to no day to day benefits. Then Rosina from Netcare accounts department started to make contact with me, I informed her that I am awaiting a motivation letter from the casualty doctors as I am busy with my medical aid as this should have been paid from my Easy ER benefits (Keyhealth). I constantly kept her up to date with my account. On the 24.02.2020 I got approval from the scheme to state that they will pay all accounts in full. I immediately informed everyone. She started sending me account 3-4 times a day I then asked her if it is really necessary as I keep her up to date with my account and we are just awaiting the next pay run for the medical aid which will be in the middle of March. She just kept on sending an account more than once a day every day. I then asked for her managers details she just blatantly ignored me and kept on sending emails every day. Today I receive a final demand on my account? Final demand for what???? For waiting that my scheme pays the account after they confirmed that the account will be paid? Is this the way you treat your patients for communicating and keeping you updated on the accounts? If I ignored you by all means I do understand but I have been trying to sort the account and keep you posted at all times. This is unacceptable
