Inability to change packages

<p>I wanted LTE because there is no adsl in my area. But at the time there was no uncapped option in my area so I chose the 100GB capped option, which was more expensive.</p> <p> </p> <p>Now Telkom has opened up unlimited to all areas, but won't let me change because it is a cheaper option.</p> <p> </p> <p>I think it is unfair that Telkom forces me into a 24 contract because of the availablity of unlimited and then when it is made available won't allow me to change. I specifically asked about whether I could change to unlimited when it becomes available in my area and was told yes. But now the staff say it is not possible.</p>
