Vodacom steeling from SA subscriber's

Vodacom are steeling peoples money ..im a using Vodacom for many years and for a while now money keeps on disappearing...everyting i call they say its active subscriptions and i ask them to cancel it. ... Now the new thing is they send you sms's how to cancel it....last week i called and they canceled all the subscriptions again...yesterday and today i recieved sms's that i have subscribed to 2 different subscriptions...but i haven't subscribed to anything.... I called vodacom again, 1 subscription of R15 /day one of R7/day etc was added to my account since last week.... So Vodacom are steeling peoples money by automatically adding these to peoples accounts... A big company like Vodacom doing this to the people of SA knowing SA people are struggling economically and alot off people are unemployed like myself.... How can this be lawful?...must we as vodacom customers go to the police?...this is theft and *********... Vodacom should be ashamed off themselves
