Unexplained debit order

<p>I received a service charge of R200 as "debit order cheque levy" when I did not sign up for this. I simply rent a Telkom line for R190, there are no voice or subscription services.</p> <p> </p> <p>I also had the first debit order bounce off my account but then it went successfully off my account on the 9th January. A rude employee of Telkom accounts called me later in the week and wouldn't believe me that the money was off. </p> <p> </p> <p>My current invoice is showing the unexplained debit levy for R200 as well as the first debit order which was paid, and these amounts will be deducted off my account unfairly.</p> <p> </p> <p>What is the unexplained levy (and please remove it).</p>
