Vodacom overcharging on monthly billing!!!

Vodacom has been charging me an extra fee every month since September 2017, for what they claim is for "vodalife", whatever that is, which i dont even know what it is. Vodacom claim i subscribed to this vodalife but they can tell me when. Well i dint subscribe to such!!. As that is not enough, every month since September 2017 they have been promising me a refund and nothing came out of their promise and they still continue to charge me every month. So far the amount is now over R2000,00. So guys be careful, looks like Vodacom has found a new money making scheme!!!
