Lack of feedback

The intiation went very swiftly but the latter feedback course of processes were not made clear, I was under the understanding that my agreed amount is the final amount, the legal lady Tanya told me that the the will let me know after the negotiations, I told her then that I can barely afford the agreed amount let alone a possible negotiated amount. I told her I went through 2 declined applications of debt restructuring, my creditors are aware I can't afford more, yet to my surprise I received an email stating that my creditors wants R1200 more, which I made very clear I can't afford, I have tried contacting Tanya and Simon countless times this past month and Noone has gotten back to me, yesterday an agent called me update me on my application process and when I explained the above she just said they will call me. If the higher amount gets debited I won't be able to live, this they all knew, I thought debt review would at least help me, but I'm back to square 1 it seems.
