Not happy with Dial Direct South Africa

I have requesting Dial Direct South Africa to send me my policy documents for over a week. Each time I am told it would be sent through and nothing happens. I call their call centre and I am made to speak to consultants who promise that they would send it through to me as well as send it to themselves in case it doesn't come through to mine. The consultants promise to call me back after 30 minutes to check if I have received the documents but they never do. Each time that I have called, which of over 15 times between May 10 and May 14, I have been made to hold over 5 mins without consideration that I am using my airtime to call them. I am really not happy about this.
