Netcare accounts.

Sometime in Dec 2019 I injured myself in the garden, and visited the Linmed Emergency Care for treatment, returning the next day again for follow-up. The service rendered was excellent and I would return to their hospital again, if the need should arise. So, in this digital age, we do not get actual invoices anymore, we just get a notification to submit payment, and the docs usually follow later. Now when I get a request for payment, I do a transfer asap. So I was surprised to receive a notification to pay.... even though it had been paid. Netcare persisted, saying that I had not paid, and so the conflict began. Proof of payment, telephone calls, the whole time consuming, aggravating exercise with an accounts clerk in the north somewhere, Nosiphiwo Buthelezi. Eventually, I called the local Linmed hospital, where I got to speak to a person who actually knew what was going on, a lady by the name of 'Sally', and to my dismay, find out that the two consecutive days are NOT recorded as one account, but are submitted and invoiced as totally different operations. At last, armed with the expanded version of the information, I was able to sort out the second payment. This could have been so much easier if the incumbent accounts person had been proficient. Lo and behold, My trials and tribulations with Ms. Nosiphiwo Buthelezi were not over. It is now four months later, many emails and "proof of payments" later, we have not resolved the issue. Is there a third invoice? Is the person really this ***********? Or is there a computer system inability to define payments received? What gets my ire is that when you eventually make progress with the matter, Netcare staff try to make it as if the delay is all the client's fault. Well, I do not run their systems, nor is it not my obligation to understand their accounts system and therefore this problem lays squarely at their doorstep.
