Unprofessional business ethics

I have been a Nedbank client for more than 20 years. I have existing business accounts and personal accounts with them. I have been trying now for 4 months to just open a bank account with them for my Family trust I registered. They cant come back to you at once with the queries they have, they just find one problem after the next and takes them a week or 2 to come back with another query and then a week or 2 to resolve the problem.I have given them all the documentation they need and still no bank account. IT IS VERY SAD THAT YOU HAVE TO BEG A ENTITY TO DO BUSINESS WITH THEM. I am seriously considering my options to move to a different bank.
