African debt Advisors Fraudulent debit order

On 9 March a lady (W) phone me from african debt advisors and explained to me that they have been appointed by the goverment to help lower interest rates where one pays loans and othebrreatail acoints, i started with thee application, but later another lady phone me to say that it isconsolidation and i then said that i kindly have to withdraw my application as a gentle man sent me a msg and said that he was my portfolio administrater named Enoch, i told him that i am married in comunity of property and that my husband declined the application as well, he promised me the application is being withdrawn, as i havent signed anything and has not submitted my id and payslip and proof of adress to them as stated in the message sent to me, it is with great shock that i found today that a debit order of R4037. 10 has been made against my bank account, this is surely fraud as i have never signed any agreemant with these people, i tried calling on the number on the internet with no luck, i now need to pay bank costs as my other debit orders also went off and there is zero fees in my account, i am taking legal action as i never authorized these people and have not signed a agreemant with them
