Absa ***** division

So today I decided to transfer money to my absa account,so I could do a few payments. Shortly after I received a call from someone alleging she was from Absa ***** department and me being cautious explained that I couldn't confirm details over the phone due to the high level of ***** at the moment and she understood and confirmed she would send a text with a reference for me to walk into the nearest absa branch ,so they could explain the nature of the call . TO MY SURPRISE MY BANKING APP HAS BEEN BLOCKED ..... I'm not happy cause the lady that called didn't explain.
