Very inconsiderate for their customers

I must say I am disappointed with the way wesbank has treated me. Last month wesbank attempted to debit my monthly installment but it bounced. When I tried contacting their offices no one picks up. When o received a statement it stated they were going to debit double which I did not mind and I ensured I had enough funds this month at the time for the debit order to occur instead they debit the same amount. They send me sms on 5th May that my account is in arrears. I would like to make a payment arrangements as now I don’t have funds anymore but their contacts number no one picks up which is why I resorted to hellopeter. These are tough times and wesbank just adding unnecessary stress
