Over Charged and no customer service

<p>I have recently upgraded my package and signed a quotation with the new amount that will be debitit. This quotation did not include any outstanding amounts from previous contract. When i received my new bill for the New contract, they included extra amounts that was not on the quote. They are charging me R350 for a handset, I did not get a new device. They are alos charging me for an extra GB that was not on the orginal quote. I have tried calling numerouse times for this problem to be sorted, i have even asked the Manager at the Vodacom Chatz branch to sort this out and he is also failing to get me any answers.</p>
