Suspected ***** - as an enquiry was done without my concern

I have received a notification from Experian that Absa Bank Limited has done an enquiry on my name on the 06 June 2024. On the 10 June 2024 I phone Absa ***** to check who has done any enquiry on my details and also trying to stop any ***** that may be in process with my details. Absa is unable to assist me because they have no idea what was the enquiry about , I am not sure what must I do if I later find our someone had used my information to commit *****, that may lead to lengthy processes to resolve while I could have immediately stopped it before completion.

I feel I am not satisfied and as a big Financial Institution they must have a system that communicates with all the department.
