My business is closed temporarly because of Nedbank's incompetance.

How much longer do I need to keep my business closed because of Nedbank's incompetence? I made an international payment to a supplier of a huge amount. According to EU REGULATION 2015/847 (which has been in affect for the past 8 years) which states that the payer's business address needs to be included in the SWIFT transaction in order for the bank in the other country to pay over the funds to the business (recipient). Nedbank have neglected to include this information and I have been battling since 29 September to get this rectified. This is a big tender I'm busy with and had to use almost all the capitol in my business account to fund this project. As I expected and planned that the transaction will go smooth and the products that I have ordered from this supplier overseas would already arrived in order for me to get paid for this tender. Currently my day to day operations are affected and had to close down my business and had to send my employees home and they are working short time because of Nedbank's incompetence. I have my lawyer working on this matter at the moment and there will be hell for Nedbank for affecting a business's operations. I will definitely switching banks. Clearly Nedbank doesn't want to walk a path with me as a business that has grown exponentially over the last year.
