Lambton Branch staff who does not know their job

We have a club account which requires 2 to sign or transact. Nedbank has frozen our account for months without informing us, we have funeral policy debit orders and investment debit order running from this account and it is quite risky to not have it functional. the 2 Committee members went to the Lambton branch and a guy who assisted them told them there was nothing wrong with our account but in the meantime no debit orders are going through, one of our Providers has actually now confirmed that the reason they cannot debit our account is bcoz it is frozen, why would a consultant miss this when we visited the bank personally to query, this is utterly disappointing and unprofessional. About time we move this stupid account to a bank who cares for its clients, you risking with our money which covers people's funeral policies.
