Two Accounts Settled Under Debt Review, both handed over for 'non-payment'

I am at wits end with Consumer Friend. I am under debt review, and have been paying my creditors directly since 2015 due to my debt counselors being useless. I have two accounts now that have been settled that have been handed over due to 'non-payment'

I requested a settlement amount on my RCS account in July this year and was telephonically informed that it is R438.80, which I paid on the 28/07/2017. A few weeks ago I received an SMS from Easton Berry Attorneys that the account has been handed over for collection with an outstanding amount of just under R500. I phoned Easton Berry who referred me back to Consumer Friend, where I spoke to several people, none of whom seemed to be able to assist. Eventually I got hold of Simiso who works with the RCS accounts, after 2 emails I was informed by Simiso on Monday 18/12/17 that the settlement balance was supposed to be R698.80 and that I should pay an additional R260 to settle the account. I emailed back on the same day, requesting a copy of the telephonic conversation from July 2017 and a detailed statement, but has of yet not received any kind of reply. I find it strange that the outstanding balance is now R260, seeing as the payment as per the debt review court order was R252.15 and I elected to round the amount off to R260 and have been paying as such since June of 2015.

I had a Wonga account which I requested a balance for in August of 2015 and was given an amount of R772.95, Sept, Oct & Nov I made payments of R150 each and phoned again in December for a settlement amount, which I was informed telephonically to be R322 and paid it on the 19/12/2015, I emailed Consumer Friend requesting a paid up letter but never received one (in retrospect I should have hounded them for one). Yesterday I received an email from HTN Attorneys that the account has been handed over due to non payment with an outstanding amount of R544.02. How is this possible?

I was informed by an agent at Consumer Friend that they changed systems a few months ago and find is suspicious that suddenly two paid up accounts have been handed over after this system change.
