Incorrect billing -data bundles not purchased added to my account

<p>At the end of November, I tried to buy a once of data bundle (500 megs for R99). I tried numerous times but the Vodacom system kept telling me that the "transaction couldn't be completed and to try again later".</p> <p>Although their system could not complete the transaction I noticed on my latest account that I have been charged 6 times R 99 for data bundles purchased. I have sent 3 emails to Vodacom's customer care department with no response. Yesterday I phoned them twice and both times the operators asked me to hold the line then hung up on me. I am happy to pay for the one bundle I was attempting to buy but I refuse to pay for the other amounts that have **********ly added to my account.</p>
