One Debt Causing me to be over indebted

I have started out with one debt last year March 2017...these people working there is not much concerned about their clients..people at the switch board don't even know how to answer their telephones..its like they are speaking to their friends outside or at home..I call and leave a message to be called back and don't get any return call..however.. I after a year of paying I found out now that one company hasnt excepted their debt councilling request and was paid their one debt amount which they worked out to pay..now I owe the company almost triple the amount which I was supposedly owing...so..they didn't even bother to find out why my interest and insurance is not decreasing and instead increasing at the company they are paying..now I'm left with a still huge debt of R11 000 still owing..all they could tell me is that its not their fault and I must just pay a few months still...they kept blaming this one and that one and telling me people that handled my profile has left the company etc etc..i should have been done paying that the reason I seeked help from One debt..instead One debt has put me further in debt..I'm sure if I made arrangements with my creditors I would have been done paying by now..I'm furious and also with the fact that I had to go to my creditors myself to find out my balances because they could not do it..they are just not much interested in their clients.. I must call them to ask about my progress because they are just not interested.. AT ALL..when I said I was going to report One Debt I was told..you can do what ever you want to..that's their attitude
