Why does Vodacom constantly Rip Customers Off????

<p>I religiously check my detailed account from Vodacom.</p> <p>This past month I found "International SMS" charges on my itemized bill, and upon questioning these charges, I was informed that it was my IPhone's Face Time App, which sends SMS's, eventhough the App is switched off!!</p> <p>After "googling" the above, I found that since March 2016 this had become an issue on the Apple site.</p> <p>My question now is why did Vodacom not inform their Clients about this "billing" issue, rather than keeping quite and monthly taking our hard earned money from us "*******ly"????????????</p> <p> </p>
