Vodacom *****ulent Contract

My details were *****ulently used to open a contract with vodacom against my name, and vodacom failed to do a proper due delegent. I called vodacom and was advised to logged a Disputes of which I did, I sent them an email with the required information I got a reference number for the logged Dispute and was advised I will receive a response in 7 to 14 days, since then I haven't received any communication from vodacom, I have sent them numerous emails asking for feedback to no avail and all they do is harrasing me with phone calls demanding me to pay the contract I never took with them. I have never owned a vodacom product and have no desire to. Please assist and intervene or direct me somewhere I can further escalate this matter.
