Debt review gone wrong.

On Wednesday 7 February while I was driving, I received a call from a gentleman who wants to talk about the pro,'s of debt counselling. Firstly i was out of my comfort zone. Foolishly I gave him some of my personal details, what a mistake! When I arrived at home I received various emails and WhatsApp that they are busy with my debt review. My understanding of debt counselling and debt review are two different actions. Needles to say I tried to contact the company to cancel the action, final approval wasn't given, the next thing my bank accounts was not available and the little money I had in my cheque account was gone. According to agents I can't cancel without repercussions. I then CONTACTED the NCR and FNB debt department who told me only the debt company can cancel the process by sending me a cancellation form to be forwarded to FNB and my accounts wil be restore.( According to them the application can not be completed without certain documentation, which I didn't provide) Please I am desperate for assistance.
