Some of them are not showing as settled.. I am assuming that they have been 'written off' as I wasn't told otherwise when my debt relief order was completed. Should I take this up with experian?

Just wondering if anyone could help me... I completed my debt relief order in March 2013 and there are a few debts that were included in it that are still being listed on my credit file. I've managed to get my credit score from very poor to poor so far.. I was wondering how I can go about getting these debts removed as some of them are still being updated regularly and i'm sure it's having a bad effect on my report. I have all copies of my debt relief order and the debts that were included in them. Is there a letter template I can use to send to them? Thanks.
