Cancelled Online Upgrade still not cancelled

<p>Vodacom direct upgraded me last year. </p> <p>I did not like the phone and cancelled.</p> <p>They collected and I have not heard from them since.</p> <p>Assuming it has been done last year, I have come to the store a year later to upgrade and now that upgrade is preventing me from upgrading.</p> <p> </p> <p>This is really bad and I would appreciate it if someone could rectify it before I go to Telkom</p> <p> </p> <p>Thank you</p> <p> </p>
