Free Upgrade of iPhone costs R7600 extra

Having an iPhone contract on SmartPlan 50 (50 minutes and 500MB) proved too little. I upgraded to SmartPlan 100 (100 minutes and 1GB).<br> I was told to wait for three months to avoid additional charges.<br> This meant an additional R40 per month.<br> <br> Next month - received 150Mb data. Then the sticker shock!<br> <br> I was told that I had cancelled the Smart 50 and was now on a SIM only deal. So have to pay a cancellation of R7600.<br> <br> I logged three cases with Telkom. Each time they said I was uncontactable and they closed them - without making contact with me at all....<br> <br> I just want the upgraded contract. I have called the call centre every day for 30 days - all very sympathetic, but useless!!!
