Vodacom not refunding

<p>I have upgraded in October which I am aloud to do as this was 22 months since I have last upgraded. I have done the upgrade over the phone as they advertise that if you do the upgrade over the phone or online it free and do not have to pay the R250 as you have to pay in store. On the 27 October Vodacom deducted R2587.80 from my account. When I call to ask what is going on the said it was the charge for the upgrade, after I said to them I have done the upgrade over the phone they said to me it was a fault on there side and logged a call so that I can be refunded. The action was closed on the 3 November and the said the money will be in my account in 14 working days, but no money has been paid back to me. I have contacted them 4 times since then and everytime they have a different story, They transfer me again and again. and no one no what is going on at vodacom.</p>
