Owing Standard Bank is a Sin...

I am owing Standard Bank and it happened that I skip my payment twice, and I received a call from a lady named Mankosha on the 07 August 2017 at 08:25AM, and we made an arrangement and just before she could put the phone down, I asked her why I wasn't receiving the statements for the account, of which she said I should go to the branch and ask them. I told her that was done and still waiting, but it seems she didn't have a response for me, so I put down the phone because she was going to. So I start receiving calls from standard bank, and they wanted me to confirm my identity and I refused because I knew it was done, and they were saying I did not instead I put the phone down on Mankosha. I received the call again on the 11 August 2017 at 13:38pm from the number ********** 404 from a rude not to mention bad manners Standard Bank employee, whom she listened to what I was telling but put a blame on me and I ended up telling her that she was being stupid because she was not interested in hearing what I was saying than judging me.
