Telkom moved me over to a sim only plan without my consent.

<p>I wanted to add data onto my contract plan. Telkom UPGRADED my contract which resulted in paying a cancellation fee. (Shows as a migration fee on the bill). Telkom CANCELLED my device off of my plan and moved me over to a sim only WITHOUT my consent at all. I went into the telkom store wanting to have more data added onto the same plan, they did just that. Then I get the bill showing I've cancelled my device and with a huge hefty fine. I DID NOT SIGN for anything at all. How can telkom just do that without my consent, that is AGAINST THE LAW. After waiting for 2 weeks to get a response from the store, im told I am liable for the charges. Even though they admitted it is a system error apparently, why am I liable for it? I did not agree to anything other than adding more data onto my plan??</p>
