Demaged note

I am extremely disappointed by a bank I had entrusted all money with as a customer. I recently sent myself money through my Capitec bank App (careless), when I went to withdraw the money, I received a demaged note. I then went into the Greenacres Capitec branch in efforts to exchange the note, I was turned away by the branch manager Duane , who advised that he cannot assist me. I then left that note with him out of fury, returned later to get resolution…. To my dismay he told me “ I threw it in the bin cause there’s nothing I could do with it”. I am highly disappointed in his disrespect and lack of customer service as a leader. He then later called me back to come fetch the damaged note, i still don’t think I want to deal with him
