Appalling customer service!

I've always sang Nedbank's praises,even recommended it to whoever cared to listen. That's just how much I've trusted this bank until now... A technical glitch on their side has cost me a lot which is still not resolved after numerous calls. Now I'm being told the only way to "expedite" resolving this issue is to go to a branch I'm not even located at because that's where the issue stems from as that's where I initially opened the account. How does it makes sense that I'm inconvenienced by this institution for an issue on their end and as their customer I have to bend over backwards to receive assistance? Spoke to a helpful gent at their call center(Calvin/Kelvin) unfortunately he had limited resources to assist however, I'm grateful for his effort. I'm disappointed that almost a week later I'm sitting with this issue, can't access my account and my debit orders have already started to bounce. The one time I need my bank to show up, I have to fend for myself. I am seriously considering changing banks at this point.
