Settlement amount being moved around to make more many out of us.

On the 30th of March this year I went on Finchoice website to request a settlement amount and made a settlement payment of R359 the same day which was provided for by their website. To my surprise they deducted from my account and found out that they sent R50 of that amount to another loan which I have with them which was in good standing still. Reason why that was done no 1 knows. I’ve probably logged 3 query/complaints with them now and no1 is actually getting back to me. They always say the matter is resolved but never give feedback and the account is still there and owing over. r400 now and they call each day. Last ref for the complaint is: 425844. I believe this is the last complaint with them then I’m going to report them to the National Credit Regulator.
