No. A debt counsellor cannot unilaterally withdraw a consumer from debt review. The NCR's Withdrawal from Debt Review Guidelines (Circular 001/2021, paragraph 7) make clear that the National Credit Act does not give debt counsellors a statutory power to terminate the debt review on the consumer's behalf.
The only recognised exit routes are: a consumer-initiated withdrawal using Form 17.W before Form 17.2 has been issued; a Clearance Certificate under Section 71 once accounts are settled; a Magistrate's Court finding under Section 87 that the consumer is no longer over-indebted; or a court order rescinding the debt review under Section 165.
What a debt counsellor may do is suspend their own services for non-cooperation by the consumer, using Form 17.W(b). That suspension does not remove the debt review flag from the credit bureaus and does not end the consumer's status as a person under debt review. The flag remains, and the consumer must still pursue one of the proper exit routes to be cleared.
If a debt counsellor has told you they have 'cancelled' or 'closed' your debt review without one of the above routes being followed, the bureaus will not reflect a removal. NDRC offers a free file review to confirm your actual status and the correct route forward.
