UNAUTHORISED DEBIT FROM UNKNOWN PERSON

The is an unknown debitor which debit R89.00 from my account twice a month. With a ref: C-NAEDO TRCK DO DISP, FNASERV/ *MY ID NUMBER*. Which scary that these4 people are actually debiting without my consent and they actually have my ID number. the other this I reversed this transaction online and I did the same at the bank. but today I again I was debited by these people.

I was advised by ABSA to call number ********** as they are the people having a feast in my account, this has been happening since from last year October 2017.
