Blacklisted for no reason

I app**** for a data contract and it was approved. Unfortunately the data was loaded on my current Pay as you go number and I didn't want that. I asked vodacom to give me a new simcard for the data contract and they told me it was impossible. They advised me to cancel the contract and then apply for a new one. I cancelled it. Now I tried to apply for a new contract and they tell me that vodacom have blacklisted me. Please help by doing the following: 1. Giving me the contract that I app**** for. 2. Making sure that the old contract is cancelled 3. Removing my name from all credit bureaus.
