Constantly have to Fica

I got another sms that I have to go to Standard Bank with my proof of residence within 10 days after I went and Fica'd my account in February after getting the same sms. Last year and the year before I had to go twice each year as well and my 4 year old sons account also gets frozen every year. It is frustrating having to waste so much time on weekends to Fica my account and out of everyone I know I am the only one having to Fica so often. Other people I know that are with Standard Bank and FNB haven't been asked once to Fica so I want to know what is the problem as I am sick of queing to show my details (and struggling to get proof of residence with the slow post office) and now 4 months apart now! It is becoming more and more often that I have to Fica! This is rediculous and annoying. My details haven't changed, there is no ******* activity going on in my account, I even have my bond at Standard Bank so I want to know what can I do to stop this. Is someone not putting my details in the system or what is the problem? Or please direct me to where I complain to resolve this.
