Nedbank does not provide "proof of payment" anymore since their system upgrade

I have made several payments from my cheque account via Nedbank's Internet Banking platform. However, I do not receive "Proof of Payment" e-mails for these payments. I called Nedbank's call centre yesterday for assistance (the call centre staff were friendly and tried to assist as best they could). They unfortunately could not provide me with the detailed "proof of payment" that I required. They also mentioned that a system upgrade had taken place a day or two earlier, and this could be the reason for "proof of payment" not being sent out. When will Nedbank eventually correct this? It is so frustrating dealing with Nedbank. After being a client for almost 20 years, I cannot wait to move from Nedbank to Discovery Bank next year.
