ABSA ALLOWS ***** TO HAPPEN

The ABSA ***** division allowed ***** to continue going through my bank account after reporting it the first time 29 November. Again same company 13 December processed funds through my account. I was told I did not report it 29 November and had to prove I reported it. I sent a complaint to ABSA and received a reference number C-***9. Then received a phone call that an investigator would contact me. Never happened. The second amounts processed 13 December have been returned however the two amounts processed 29 November which has been stated by ABSA as not gone through my account and clearly shows on statement have not been returned. How do ABSA allow this to happen? Why do I have to prove and follow up? After 30 years with ABSA it is time to move on
