Account Frozen UNACCEPTABLE

Today 28/02 - month end - I went into my account to pay someone and was advised the transaction had failed - account frozen. this was at around 09:00 I called the number on my profile and was advised that they would put me through to the FICA department as I had not Fica's my account. When I spoke to the FICA person and asked when and how I was advised to do this, they said it would have been via SMS. I did not see this SMS - I get a lot of Nedbank advertising / Green back etc SMS and scan through them . If I had been made aware I would certainly have actioned whatever I needed to. No-one called......what is a private banker use! Just freeze the account without advising the customer. It is now 13:30.....I called my private banker...call declined and he said he was sorting it out. 13:32......whatsapp message received from private banker" ""The above matter has affected many clients, I apologise, and currently tending to as many as I can, yours has already been submitted for certification, I will advise as soon as completed."""" So I sit and wait for Nedbank. There will be no compensation to your customer for the serious inconvenience and I am still waiting to pay accounts. My reputation is at stake. How do I explain that my bank has frozen my account without any waning. UNACCEPTABLE!!
