Vodacom over charging, requested break down and bill audit but 2 months later and still they've done nothing!

<p>Vodacom has been doubling my bill every month now, I have been on contract with them for years and my bill has always been in the 2K area. Then I get my July bill which has suddenly gone up to 4,5K, this was followed by the August bill of 7,5K. Nothing has changed with the way I use my phone so why is it costing me so much more now every month?<br /><br />I've contacted them several times about this and they can never tell me why it's gone up or what it is that is costing so much. After hours of multiple tranfers and repeated conversations over the phone with their so called support, I eventually get told (every time) that they will have to get back to me after investigating, but they never do.</p> <p> </p> <p>I've requested the break down so I can see what's going on but they say they can't give it to me, I've requested an audit on the months in question but they never do it.</p> <p> </p> <p>How can Vodacom get away with this? I've been a loyal customer for over 5 years and have had multiple contracts with them and they just going to do me in like this, without any explanation, I can't even get a break down of my own bill or even a call back to let me know what's going on.</p> <p> </p> <p>If any one has experienced this with Vodacom please let me know how you resolved it because clearly it was not through their "Customer Support".</p>
