Poor service...they even make it impossible to cancel

<p>I have iburst data line installed at home. Since being installed it has been a nightmare to deal with them. The speed of the line and trying to get wifi throughout the house been impossible. Eventually we spent over R5000 installing additional equipment to improve the speed!! Not that it has helped. The call center is useless, so I send emails to their service centre...my first email they call me and state they will respond and then never call me back. It has been so difficult to deal with iburst, that I have decided to cancel. I have sent a number of emails to cancel and surprise surprise they have not responded and no one answers the call centre number. Feeling helpless.</p>
