Monthly Edo Attempts to rip me off my FNB savings by Intec College

Intec College Pretoria Central 273 Thabo Sehume St. Contact: **********

My sister has cancelled her registration at the private college in March 2018. I have exchanged multiples emails with the school containing receipts and confirming that my sister is no longer apart of the school and she does not owe anything. They have confirmed my emails and the status of my sister. 12 MONTHS LATER i AM STILL RECEIVING MULTIPLE EDO ATTEMPTS ON MY ACCOUNT AND SINCE LAST YEAR INTEC COLLEGE has been informing me the process to remove the debit attempts takes a while (For how long??), FNB (my bank name with the school) says they are unable to cancel any debit order that has never been successful. AN AMOUNT OF R680 THIS IS UNACCEPTABLE!!
