ABSA wrongly emailing me other customers' statements monthly

For the last few months, someone at ABSA decided to load my email address as the contact email for several customers that I do not know. I keep receiving monthly statements for various different people and despite my complaints and over 10 case reference numbers saying someone is dealing with the query, they simply close the case and this continues. How can ABSA continue this breach? I can't block it because I need to receive my own personal statements but there are customers out there not receiving their statements because they are being sent to me and ABSA staff to refuse to correct this POPIA breach. Can someone at ABSA please assist?
