Froze all my accounts and my wife's accounts because they refused to update my tax info that I offered 3 times.

FNB started sending me messages to confirm my tax info. I did so online twice and still kept getting messages so I contacted them via secure chat and was told that the problem is sorted and to ignore any messages. So I ignored the next message and they shut down ALL my accounts and my wife's accounts. Online banking gave NO indication that my accounts were frozen and after filling in all the details to make a payment and confirming the transaction with my phone, I got a useless error message that does not tell me what the problem is. I tried twice more and ecen tried to add the persone as a beneficiary and kept getting errors. So I went to the ATM to draw cash to pay my garden service and could not draw on any of my or my wife's accounts. This time the statement indicated that my accounts were frozen. This is 3pm on a Saturday so I contacted secure chat and the lady could at first not see a problem on my wife's account until I gave her the card number and only then could she see that because we have linked accounts, all hers had been frozen too. So I was at the bank at 9am on Monday morning and asked to speak to the branch manager. He came and asked what the problem was and then went to fetch his laptop and tried to fix the problem. He then wanted to verify my thumb print so tried to log on to the PC in the room. Soemone else was logged in so he had to re-boot the PC to get in. He then tried to connect but could not. He eventual found another person that came and managed to get me verified after I had been there for nearly an hour!!!!. Then they told me that the hold on my account had been released on the Sunday and that my account was cleared. He went with me to draw cash from my and my wife's accounts and that worked. He then gave me some forms to complete if the problem happens again. I went home and then tried to make a payment to my garden service and it failed again. I Contacted the Help Desk and the lady told me that the hold was back on my account. She then transferred me to the tax compliance desk and after much time, she finally managed to clear the problem. The 'branch manage' gave me a phone number to call if I had any further problems. It turned out to be yet another help desk that just hangs up on you when you make you selections. So it cost me 4 attempts to make a payment, two trips to the ATM, 4 hours in the bank and another hour on thge phone to sort out this problem. I am retired and have had no changes to my funds or tax status for the past 14 years so why they should all of a sudden demand me to verify my status (which I did 3 time, both online and talking to a help desk) and then to shut down all my accounts and all my wife's accounts as well for good measure. They completely embarrased me when I could not pay for services rendered and cost me money to sort the problem out. I know the other banks are not any better but I strongly advice not banking with FNB
