Information on my Absa profile/account changed without my Knowledge and Consent

I discovered that the information in my profile was changed without my knowledge and consent in my ABSA account. My title was changed and my address was changed on the entire profile to one of the properties i recently bought . When I contacted ABSA they said they cannot tell who and how it happened, ,they said I should follow ABSA processes to rectify this i.e. bring documents to change what was changed by ABSA without my consent . While i can do ABSA processes to change back the information , I don't understand that someone in ABSA can change information in the entire profile and then I should be responsible to rectify that

I have banked with ABSA for more than 30 years and most of my investments are with ABSA . One other disappointment is that ABSA consultant on ABSA ***** , stated on record ,that this is not ***** - but she this issue as a mere complaint .

I was so frustrated and informed her on record that i am escalating this matter in all platforms as i feel strong that this more than a complaint. I cannot do urgent transactions through the ABSA account , because i will be providing the person I am making business with - incorrect information . I am very worried that , if it is so easy for information to be changed in my profile -affection all accounts , without my knowledge and consent , what else can happen to my account , within ABSA without my knowledge . Does it mean that processes of authentication and verification in ABSA applies ONLY to client's requests , and not when ABSA stuff decide to change things on client's profiles ? I am frustrated
