Nedbank very bad service

On 29 March2018 our small business account with Nedbank was frozen without any communication from the Bank . This was despite the fact that the account had been with them for 27 years . When I contacted their call centre, I was informed that we had not comp**** with their FICA requirements . I pointed out that I had been dealing with their small business manager since 5 March 2018 and had submitted all documents requested . It then transpired that two further documents were required which had not been requested by them . One of the documents had in fact been handed to them 9 months ago ! It is now 11 days since the account was frozen . During this time I have spent well over two hours on telephone calls to their Proffessional Services section, Complaints Division and FICA Division in addition to lengthy emails to the small business manager . Three emails to their complaints division have gone unanswered . The fact that they have effectively shut down a small business that has financial and VAT commitments without the courtesy of a phone call or email is disgusting and amounts to abuse of the customer . Even knowing that the fault is on their side they have refused to clear the account . What is apparent is that they have a small army of very polite staff where no one has the authority to make a decision or take effective action . I do not believe they have the ability to handle my affairs going forward .
