Thank you for your question.
What you must keep in mind when your debt review is cancelled is that your debt review will be listed on your credit profile until a Form 19 is issued. This can only happen when your original installments according to original contractual terms can be maintained or if your debt is settled.
If you are having no luck communicating with your debt counsellor we would recommend you lodge a dispute with the Credit Ombud (Here is a link to their page explaining the complaint procedure) or the National Credit Regulator (Here is a link to their page explaining the complaint procedure).
Hope this information helps.
