SHOCKING CUSTOMER SERVICE!!!

Yesterday I phoned FNB to have a debit order reversed on my revolving loan. I was on the line from 09:00 to 10:30 and was transferred to 4 different departments. After all this nobody was able to assist me. This was the most unproductive and frustrating 90 minutes of my life. I have never experienced such incompetence before. Every time I was transferred to a different department I was on hold for at least 20 minutes. How can such pathetic service even exist. I cannot put into words how shocked and angry I am with FIRST NATIONAL BANK'S customer service.
