Bad service

<p>I received a sim card and wasnt aware that it was a contract sim. i have been trying to cancel the sim for the past few weeks and have called the call centre on numerous occasions only to have to wait as their lines are busy. i have sent about 4 emails and still no response, i was charged R 350 for something im not even using, this is unacceptable and will be forced to close my account if this is not sorted out soon</p>
