FNB Pathetic service and account management!

FNB started sending me sms messages that we need to update our Fica status. I phoned FNB and was guided through the process to update my fica status on their banking app. I then received a reference number to confirm the process has been completed. Late yesterday afternoon I receive a message that states that my account is now frozen. I tried phoning but no answer. Early this morning I get hold of a FNB banker that informs me that my account has indeed been frozen. I then quote my reference number which he couldnt check. I then had to verify all my details again to have the account active again. This is totally unacceptable for a business account to be frozen when I did what was asked from our side. I pay for a service which they decided to revoke. I will take this matter up with the banking Ombudsman and I will move all my account from FNB. Pathetic service!!!!
