Client services drop call on customer

I received an sms yesterday of a new debit order that went off on my cheque account and when I called the number on that sms to dispute and stop that debit order the number cuts off and doesn't go through. Eventually I log on to the FNB App to get the contact details to call and are being on the line for approximately 10 minutes on my cellphone, I get through to Amanda whom I explain the situation then I don't know what she pressed, I hear an automated voice saying "transfer" then the phone line went dead and the call dropped. So after going through all this no bother tip even call the customer back. This is ridiculous.
