Nedbank not treating customers fairly

Im writing on behalf of my mother regarding her bad experience with an investment account from Nedbank. She opened an investment account which was due to mature in October 2020. When she went to a Nedbank wonderpark branch she was then told that her investment account was discontinued and they had therefore thrown her savings into a 32days account. Their excuse was that they could not reach her hence they took a decision to place the funds into a 32days account, Which has much much lower returns! I believe she was not treated fairly. If a mere phone call was impossible, her postal address was noted on her policy documents and an effort to inform her in order to make a decision was an option which Nedbank failed to make possible. To make matters worse, my mother requested for all her funds to be deposited in her ABSA account as she was now miserable and without options, they inform her that the funds are too large to be deposited and so she will have to open a Nedbank account! She does not and will not open a Nedbank account. This will be reported to the Ombuds if no action is taken. My mother was definitely not treated fairly.
