FNB Call Centre - Laughing at their customers & cutting calls

Pathetic experience from the Debit Order dispute department - This agent first mocked me when I asked who her name was then laughed at me after accepting the terms and conditions. She was so unprofessional and exasperating, when I asked to speak to her team leader, she asked for my number without explanation. I asked why and she said so that they can call me back - I asked for their name and the reference number for the call & my call was cut off Yes, she didn't call back as she just took my cellphone number and neither did their manager call me. I am so livid with Fnb, first of all they didn't ask me to approve this debot order before it went through and now their call center service is humiliating!
