Contract has lapsed but I'm still paying the same price?

<p>My contract ended 2 Dec 2016. I haven't canceled it but i expected my monthly instalment to drop as I am no longer paying for a handset until I upgrade after the Samsung S8 comes out. The instalment has not dropped. I call the call centre and speak to the most clueless person and i end up with no answer. Why is my instalment still the same? And if I'm going to pay this much for a paid up contract kindly cancel my contract.</p>
