Continues FICA blocking

I went to the bank for FICA in Sep 2015 as absa required my documents for FICA. 4 months later, they block my account so i went to the bank to find out why my account is block. ABSA said they need to FICA my account again without any sms, email or any notification. After i FICA it, a week later (26/01/2016), ABSA block my account again when i want to do internet banking. I phone the call center, and they said i need to do FICA again. And they cannot answer why do i have to FICA so frequent. Why ABSA DO NOT inform their client? Other bank only do FICA once a year. ABSA requires me 4 months, then 2 weeks and then 1 week. This is RIDICULOUS and EXTREMELY FRUSTRATing
