Inconsistent Rules and Requirements

I just came back dissapointed and confused from Nedbank Goodwood Mall. I have a club account with two other members and we were told that we need 2 signatories to withdraw and indeed we withdrew in March with 2 signatories. As a matter of fact, I have another club account with Nedbank and I have drawn money from the account with 2 signatories.

Well today I was told we need 3 and the teller, Sandy Joseph, said that the system says so and even her supervisor won't allow it. I'd like clarity on this because it's a big inconvenience as we had plans to use the money today and people to pay. There is also the issue of the bank going against its word.
