Nedbank the poorest bank of all banks

For more than 2 weeks I have been waiting for this bank to release an international payment instruction from my company to a supplier abroad. This bank and its personnel have no clue what they are doing. My so-called banker (Leroy Jacobus- Brackenfell Branch) is never available, always on some kind of training, yet he does not know how to treat clients or know his products. The specialist (Hugo Truter) who is assigned to do the international transaction is hardly available and does not give proper details when they need information pertaining to the transaction. Every time there are more and more details that my company should provide them with...it seems as if they too are still in training in how to do international transactions. This is the last time I want to do business with a bank like this. If this matter is not resolved asap, I will have no other choice as to lay a formal complaint with the Ombudsman as I am losing money because of Nedbank.
