Poor service

<p>I really don't understand how do they operate about a month ago I complained about their billing regarding my tablet they promised that they will sort it out I will pay R129 the following month but that never happened they debited R148 and they are saying I'm still owing them another R148 ,I want this contract to be cancelled I want nothing to do with them,they can just debit their money,I'm sick and tired about complaining about the same thing all over again</p>
