If you are under debt review then you should get a statement via your Payment Distribution Agent every month. This will tell you where your money went.
While they might look a little different to what your credit provider statements show, you should see the money come into those accounts.
It is good to check and if you see something that confuses or worries you, then reach out to your Debt Counsellor (and send them the info and a detailed explanation of what appears to be the problem).
They can investigate for you and help you sort any possible problems out.
