Continued Billing/ Incorrect Billing After Contract Had Been Cancelled - For the second time!!!!

<p>I am extremely irrate with Vodacom. My contract came to an end in October and I called them in September telling them i DID NOT want to renew my contract. I was offered a 1 gig contract for R75 a month which i signed and was told would start deduction at the end of October. HOWEVER, even after my contract ended and I requested that it be ended, my account is being debited by R350 and not the R75 that i was promised and it has happened for the second time TODAY. I also called one of your call centre agents and they were unable to help me because "the systems were down". I want this sorted out NOW!! </p>
