Nedbank billing error - consultants can't read

I've been trying to resolve double billing on my account since 27 March 2020.

First they've blamed the company who processed the payment. And this company has clearly shown (without dispute from Nedbank) that Nedbank is at fault here. Why Nedbank plays for time like this is beyond me.

Nedbank just can't keep the information I send them together and keep asking a new detail (that I've already sent) as a reply to each communication.

In the last email the consultant literally re-asks what the transaction date is when I can clearly see the date and amounts specified in the thread showing my previous email to her. I've used plain text. But it seems either Nedbank has systems that remove the info or they employ people who can't read. Either way the result is that Nedbank as a Business communicate with the literacy of a 3yo.

I have repeated myself ad-nausea for months.

So today 20 July 2020 I'm still waiting for them to refund double billing from 3 Feb 2020.

And they are still drawing Interest on this billing error since then I'm also looking for interest on this amount to be calculated and refunded.
