Cannot open sign up for Private Banking

I were sequestrated February 2011 and I appreciate that the sequestration had a negative impact on my credit profile. I have however been rehabilitated and my situation has changed substantially from 2011, to the extend that I qualify for private banking. I tried to apply this morning and on my profile the risk was displayed as zero but the FNB system still declined my application due to historic accounts on the system from the time I were sequestrated. What is the purpose of showing good behaviour and getting rehabilitated if you are still not being helped.
