Don't upgrade - just change provider!

<p>So finally someone phoned me to assist with an upgrade.</p> <p>It is now nearly a month later and I am still not able to use the new phone....the sim has been 'blocked' by vodacom.</p> <p>I was assured there would be no additional charges to upgrade, but an invoice of R971.15 was charged!!!!!!! I have requested this to be reversed, being told it will take about 7 days. Still nothing has been done!</p> <p>Trying to get help is impossible, I have been sent from upgrades to call centre (and cut-off) more times than I care to remember!</p> <p>When did the service become non-existant!?</p>
