Debt busters, busting my *****

It's been a bit of a nightmare. At the end of last year I got severely ill and this put me out of commission for a loooong time. So trying to get back on my feet I filed for debt review but quickly realized I couldn't pay it as I liked. In the end though I finally managed to get payments in. I was still owing but I was working hard towards squaring what I'd missed - except by the time I paid them around 10k altogether I'd noticed the funds were not going to my debts at all. In fact I constantly got complaints from my debtors and in the end I had to pay them all myself anyway. I've been trying since the 15th of this month to cancel the review process without much luck. They simply aren't picking up my phone calls or even responding to my emails. All I get is empty promises and beinf put on hold. I'm hoping that today there will be some improvement. If not I will be debited again, this time unnecessarily as I'm trying to cancel my review. Not sure what to do here. This is the worst service I've ever experienced
