Unknown debit orders

This all started in 2013 when my capitec account was debited on a monthly basis by a company named NAEDO,I contacted the company trying to find out why i am being debited without permission but i could not get hold of them,i stopped using my capitec account since my money would disappear,there was no specific amount debited they would take everything i have,even now on 9March 2016 i made a statement and still saw NAEDO appearing,i just want them to stop debiting me and pay me back the money they took on my account
