No, MABS are not a debt collection agency – they assist people that are in debt & contact their creditors to try to come to repayment agreements with them.
If you needed someone to contact your debtors you would need to employ a debt collection agency.
MABS will contact the people to whom you owe money and try to come to a payment schedule with them.
They can also set up a Special Account with you in the Credit Union whereby you lodge money to your Credit Union and the CU will pay your creditors per the schedule.
