Some problems

<p>I've got a few lines with vodacom.</p> <p> </p> <p>My first problem is:</p> <p> </p> <p>One of my lines is a 20GB data contract. I've got a R50 call limit set to this line. Every month I get charged R65.96 for something called content service. What is this and why am I getting charged extra?</p> <p> </p> <p>2. I don't know how many times I've asked Vodacom to just send me a invoice at the end of the month so I can do a EFT. It's the 7th today and I still haven't received any invoices.</p> <p> </p>
