Nedbank Ignoring Client Concerns Regarding loss of Personal Information

As of today, Nedbank still have not responded to my complaint of 15 Feb 2020 regarding their unacceptable loss of my personal information. I requested a meeting with my local branch manager to discuss my concerns but he just passed the buck by "bouncing the request up the corporate tree" and I am still waiting for someone at Nedbank "higher up than my local branch manager" to meet with me. The high handed way that Nedbank are treating their clients whose personal information they lost is astounding. It seems that Nedbank think that the concerns of mere individual clients do not even warrant a courtesy response let alone actual action to remedy the concerns. How inappropriate can you get!
