Incorrect Billing

On the 23rd of January I contacted the call centre regarding incorrect billing on my account. I was requested to send all the required documentation through via fax which I did. On the 15th of February after still not receiving any feedback I contacted the call centre again where I was advised to call yet again another call centre. I sent a complaint to the e-mail address listed for Vodacom complaints on the 15th of February. ***, up until today no one has contacted me yet to resolve my complaint. Who can I contact to have this matter resolved.
