Cell C upgrading clients contract without clients approvals

<p>My contract with Cell C had expired, the call center agents kept on calling to ask if I wanted to do an upgrade and I always refused. A month later when the bill came it was R170 more than what I used to pay. I went to the Cell C branch in Welkom and they told me that my contract was upgraded and I wasn't even aware because I've never agreed on any upgrade. So I placed a query with cell c on the 8th of july, till today I still have not received any feedback. I keep on calling, they keep on telling me that they will escalate my query. I can't afford this contract, every month It debit order bounces and I get charged for late payment. </p>
