Unfair listing on Experian

Good day

My employment application was declined because Absa bank listed my name on Experian because my cheque account was misused for R500.00 which i was not notified, according to NCA before you list someone you need to notify the customer about your intentions with 20 working days in my case i was not notiefied wich lead my employment application being turned down because i owe stupid absa bank stupid R500 for misused of account which i was not notified about. (i dont even know what is that misused account list is) i regret openning account at absa and i will never associate myself with this bank even my family and friends will know about this stupid bank but i will dispute this listing with experian and Oumbudsman.
