Blocking Account without notification

My account has been blocked twice within the space of 2 weeks without notification on both occasions due to a FICA problem. The 1st time occurred around the 24th of September of which i was greatly inconvenienced and i had to go to the bank of which i was served by Brenda Sello, of whom was not very helpful and posses a very bad customer service approach she is arrogant and does not listen to the voice of the customer. As much as it is law for the bank to block an account which needs to be FICA'd due to permit reasons notifying a customer will only improve the quality of service and bank experience of the customer. i am not the 1st one to complain about this very issue, meaning the voice of the customer is not being heard. This is a very serious issue and could be a matter of life and death, a simple email or SMS from the customers cost will serve as a reminder for the customer to approach the bank before they are inconvenienced into needing funds desperately. It has happened for the second time within 2 weeks of which i did submit all my information and my account was reactivated, now it has been blocked again without notification? Please help me understand.
