Vodacom-Pathetic Service

In March a debit order went off my account from Vodacom. I immediately reversed the debit order, as I have no accounts with Vodacom. In April a second debit order came off my account. This time I phoned the call centre and they informed me that I have a contract with them. I asked for the contract as I immediately realised someone committed *****, but only received a quotation. So a contract was issued to someone, without proof of address (address incorrect), id (name on contract incorrect) and verification of bank account or bank statements. The call centre told me to email a copy of my id, 3 signatures and an affidavit to the ********** department, which I did. I even went to a branch so that they can also email it from their side. After all of this, I am now awaiting on Vodacom's feedback regarding this case. To make this situation even worse, I now receive a phone call every second day to tell me my account is in arrears. To every call centre operator, I have told them the story and provided them with a reference number. I asked everyone to make a note on the system, to not phone me as this is an ongoing case. How long before I can get finalisation on this matter? I think it absolutely pathetic that this is now going on for 3 months and no one can give me an answer or resolve this matter.
