Should you reach a stage in your life where you are unable to pay back your loans, a debt counselor will assist you in negotiating with your creditors (the companies you owe money to) to reduce the amount of each instalment and pay your loans back over a longer time.
With debt review, your loans will be paid off faster than if you were to be placed under administration. There are, however, consequences to debt review that everyone needs to know about: you can't apply for credit while under debt review, it is costly (around R8000) and you can't be released from debt review until the terms of the agreement have been met.
