Charged handset installment but on sim only packages

<p>I changed my contract August 2016 to sim only as I am still happy with my current device. Vodacom was suppose to stop billing for hand set installment by November, they have never stopped. The amount R 350.88 is sill on my bill from November till today. I have called numerous times (can't even count anymore) have talked to so many people that either put me through to different departments that never answer, place me on hold and then drop the call. I have been to Vodacom stores and all they can do is call the call center! I need this to be resolved ASAP as the amount that needs to be credited is well over R 2000. I know none of my queries or complaints have helped because the handset installment is till on my statement each month. If this amount is deducted again at the end om the month I will need to stop the debit order as I see this is the only way that Vodacom will pay attention to my query!</p>
