ITC Listing over a ********** account opened under my name

I was contacted in July by a collection company, regarding a Vodacom phone contract account that is overdue, and owing ZAR 29,000.00. Except I do not have a contract with Vodacom, and I have never even attempted to apply for one, even the phone I have was bought cash, and it's on prepaid. The lady who called advised the contract was taken out on the 29/09/2016. I went to their branch in Clearwater where I requested to see the documents used to apply for this contract, as well as a signed contract, as I had never lost an ID or Drivers Licence, and I believe whoever made this application had to produce some form of identification. They could not provide me with the documents, all they could pick up was the following address: 1066 Bogatsu Street, Dobsonville, Soweto, Contact: ********** . I have never in my life lived in Soweto, or had that contact number. They could not even pick up which branch the contract was taken out from. I was then advised to do an affidavit, and bring a copy of my ID, which I did and they were forwarded to the ***** department. I have only received a call once from the ***** department advising they have received the documents and they are busy investigating. Today 18/09/2017 I receive a call again from the collection company advising that I am liable for the costs of the contractual amount owed, I try to explain to the guy that my case is with the ***** department and still under investigation. He informs me that the reason he is calling is because they have concluded that I must pay for this account, I asked him why has no one contacted me about this? he cannot give me an adequate answer. How can I be liable for a debt that I have not app**** for, and how was this conclusion reached, that I am still liable? Even after I had informed them that the address used for this application is not even mine. They cannot give me the documents I requested from them that were used for this application, I need a copy of that ID document used, I need the signed contract so they can compare the signature used to mine. Also, why now when the account has accumulated to ZAR 29,000.00 am I hearing of this? How was it allowed to go on for this long without being payed, without anyone trying to make contact with me about this? I asked how they got hold of my actual contact details, and they advised they used a tracing company, surely that tracing company could've been used in the 1st 3 months of payment not being received. Not wait a whole year before making contact. This whole issue is making my life difficult as it means I cannot apply for any credit, and I cannot move from my current job because of the listing. My life has been put on a stand still. Instead of doing proper investigations, and working on preventing further ********** cases like this, I am now being chased to settle a debt that has absolutely nothing to do with me.
