Mr. Vleis Visagie is from ABSA?

I had an interesting phone conversation with a Mr. Vleis Visagie. He claimed to be phoning from the bank which he claimed to be ABSA. He claimed to be from the IT department working with developers. He has access to valid confidential personal information. He rambled off about medical aids, pension funds and private portfolios. This concerned me as I have not authorized ABSA to give any private information to any third party. I interrupted his rambling and enquired where he got my personal information from. At this point he started shouting and told me that I have a “***” attitude. I ignored this and again asked him where he got my private information from. He then called me a “doos” and a few other profanities. He stated that it seems the people of Witbank has an attitude problem. He stated that he will come to Witbank and threatened to “ram my head through a wall”. I asked him again where he got my private information and what company he represented to which he responded that he was phoning from the bank followed by stating that “Jy is ‘n doos” then he ended the call. The call was made from +***. If this is an employee of ABSA I’d like to complain about his behaviour. If not I would like to know how he got his hands on my personal information from ABSA. Either way I am not impressed.
