POOREST SERVICE EVER

How difficult is it to get an invoice sent out to a customer? I'm send from pillar to post by customer care agents. The poorest and arrogant personnel. I was using your company for the first time and DEFINATELY for the last time. I'm still shook by your poor of the poorest service. I can't even get through to your branch in Cape Town Airport. YOUR SERVICE IS THE ****TEST, APPAULING, SHOCKING.
