Vodacom not cancelling my LTE contract as asked, begged!

This is my umpteenth attempt to get Vodacom to actually respond. They post on Hello Peter that they respond privately but they are lying to the public. Apparently they had to OUTSOURCE all the cancellations because there are too many people wanting to cancel their contracts and gave them order to drag every cancellation as long as possible. In order for them to collect money from us as long as possible. I went in to Menlyn, not even they can help me as it is someone else who does the cancellations. I.ve been asking for months to have my LTE package cancelled, I still pay R650 per month!! I want a refund!!!
