Not giving me the data I pay for.

<p>I get charged a 300MB SERVICE FEE R 74.56 each month but I never receive my 300mb of data. This has been going on for 8 months now. </p> <p>I call the callcenter each and every month to get it resolved, but nothing ever happens. I've also logged multiple tickets to get it resolved, with no result.</p> <p>I give up with MTN</p>
