Device already paid off - but still paying

<p>I signed up for a new Smart Plan 100 contract with a Samsung Galaxy Note 4 in December 2014 and was paying that contract for about 5 months before migrating the contract to the Unlimited Lite package in June 2015 at the Somerset Mall Telkom branch. I was informed that the Device instalment fee will fall away after the initial contract reaches its 24 months term. That term has expired in December 2016 already and I am still being charged the R400 device instalment fee.</p> <p> </p> <p>This needs to be attended to and removed and I need to be credited for the payments that should not have been charged.</p>
