Account frozen every two days

About three weeks ago I tried to make a payment from my bank account at about 17:00 only to discover that Nedbank has frozen my account (due to FICA and AML which was done and accepted in November). I phoned my business manager who couldn't assist after hours. I then phoned the call centre that could not assist after hours. Finally my account was unblocked the next day, but my account is being frozen every 48 hours. I have now lost one of biggest corporate clients as I could pay for their urgent flights up front. I have sent 3 complaints emails to the Client Feedback email address and I am yet to receive one email or even an apology from Nedbank. I have now lost a huge chunk of my income and if I can't do damage control will have to lay off staff to keep afloat. Nedbank - your staff is going home with their salaries at the end of the month, but this lack of service and lack of care is ruining peoples lives! This is NOT ON!!
