Interest Rate for customers under Debt Review

I'm currently under debt review and I had an overdraft on my FNB Account. The final order was granted by the court in Feb 2015 with the new proposed interest rates accepted by the FNB. To this date, FNB had not changed the proposed interest rate on their side. I sent through a query towards the end of July to query the interest rate and to this day, no feedback or email from any of the FNB consultant that is dealing with my query. The only time I get feedback is when I have to call and enquirer from the Premier Banking division, who they themselves have to go and enquirer from debt review section and give me feedback. So far, nothing has been done to this account and no formal or informal communication or feedback as to the progress or acknowledgement of my query from them. No one has even admitted if they are at fault or not or they are fixing the mistake.
