Vodacom Online is a ****

The vodacom online service give phones to any one on your account without permission from the main account holder. How is that possiible. If any ons on my account goes to Vodacom they cannot do so, because U have to do it, but the online service phone them to tell them they can upgrade so they ordered a new phone. I receiced a sms to say there was a new order *** and if it is not me I should phone vodacom customer care. I phoned and the could not pick up this order nr. They blocked any online services on my account for 6 months. But this person allready received his phone, I do not even no what phone it is or what the amount would be. I refuse to pay for this. The online service phone me and everyone on my account 6 times per day, I do not have a contract with them, I only upgrade in store. If vodacom cannot assist me I will go to another network, I am part of Vodacom for more than 20 years and pay more than R6000 per month. I have tried to cancel some of my contracts, vut that is impossible
