Vodacom Charging unapproved costs on account

<p>During the past months I have seen costs on my invoice which I have not approved. vodacom says its content services that I accepted while on the internet. I did not sign any agreement for costs? How can you just charge me for something that I did not sign and accepted. I am utterly disgusted that vodacom deals with these companies and allows charges to accumalate on my account. I will be leaving vodacom very soon, they are gone very greedy and lost customer satisfaction.</p>
