Paying for a contract that no longer exists

<p>My father has 3 different accounts with Vodacom, we have been trying to sort out this problem for months! in Dec 2014 vodacom automatically opened up his 3G data to an open status and added up a huge bill. Without authority from my father. Numerous phone calls and nothing has been done! The phone number has been blocked as well as the other 2 numbers (which are used for business) the number is under investigation yet for 3 months we haven't heard anything and they account is still be debited. This is unacceptable vodacom! </p>
