Unprofessional call center agents!!!!!!!

I called in to change my debit date on m personal loan and everytime someone tells me to phone a week before, on the same day and now only on day after the debit has gone of..... Then the agents tells me directly I'm STUPID...... NO Wonder I have changed to standard bank... ABSA you are going to lose more clients regarding the pathetic and unprofessional service you supply to your clients.... Get professional agents on the call center floor.....!!!!! OMW you agents in the call center actual disgusted me.... And then I ask to speak to someone in Afrikaans they tel me straight if you can't speak English then sorry we can't help you.... ****** on its best!!!!!
