Vodacom please stop *****ing my airtime

Vodacom keeps subscribing me to Vodacom Live! subscriptions without my consent. I have never subscribed to any Vodacom subscription service. I have never received any double opt-in emails or sms to confirm a subscription. Yesterday I found I was subscribed to no less than 5 of these services (not one opt-in was received). I went through the motions and cancelled all 5. This morning I find I have been subscribed to another 2 Again I went through the motions and cancelled both. Within 30 minutes I had been subscribed to another 2. Once more I went through the motions and cancelled both. This is ridiculous. Vodacom is shamelessly *****ing my money without my consent. VODACOM PLEASE STOP YOUR ******* SUBSCRIPTIONS!!!!!!
