Dissapointed

Had the worst experience of my life with this bank, they froze my account without sending me a notice just because I haven't taken my documents for FICa to their branches. I updated my FICa in this year already and I'm asked to do so again. The previous time when I went to submit my documents, I went to Randburg square branch and told them I was there for FICa and they all didn't know what was that, I then called the call center and they told me to take the documents with and show them the message, I went back again only to be told that it's something they don't know I should call a different department, they gave me a number to call and I did so, still got referred to any branch, I then decided to change branch and went to oak avenue I'm Randburg, they also didn't know what that was about, I explained to them the whole story of my ups and downs, and took my documents and made copies. My question with nedbank why do you state that I shud go to any branch and submit docs yet your branches know nothing about it? I have incurred a lot of costs coz of this bank, I have debit orders that go thru, I decided to go to them and give them my other account details to avoid what I have gone through, unfortunately one of the debit orders went through, hence I had to transfer money into that account? I'm not allowed to do eft, it says the account is frozen, tried another option to deposit same thing and in the process I got searched and lost R500 all because of the inconveniences caused by this bank,
