No service / assistance with a incorrect contract

<p>I took out a contract from vodacom and requested to use my current number. 3 Weeks later no sim swap have been done. I took everything back because they claimed it was a error from their side and that I should take a new number which I cant. Now they are currently debitting my account for a contract I do not have. After they said the contract will be cancelled. Every month the amount for contract is debitting and they giving me no assistance at the branch. After more than 20 calls they just say they'll call me back but never reapond to me. Anyone who can help me with this,I will appreciate it dearly.</p>
