Contract Cancellation not done

My contract with vodacom at the beginning of 2015, i was sent an sms by vodacom saying i will be put on a new contract as of 1st of June 2015. I called them at the end of May to let them know i didn't want the new contract. The lady i spoke to me offered me a data bundle contract (2GB per month for R109.00), which i accepted and she said the would not be activated. At the beginning of June, I called vodacom several times telling them that 75 minutes, bundles and smses have been loaded on my number even after i called in to say i don't want another contract except the data bundle one for R109. The reference numbers I was given are *** and TSH0105.<br> <br> This morning i realise vodacom has taken R612 from my bank account and 75 minutes,449.99 MB of data,239.04 MB of night owl data bundles, 393 SMS have been loaded on my number again and I'm on the smart s package. I called again, they tell me they are experiencing issues. When i check on account summary, 2GB MBB 24 month - TopUp shows as my current plan. How can one plan appear on my profile but i'm being billed for another account and minutes are loaded I didn't agree to. I have all documents to support my claim.
