Failure To Close ********** Account.

On the 6th of July 2017 I discovered that a contract account was opened on my name without my authorization and reported the matter To vodacom and I was given a service request number(EC-0CTF-28TSAQ) after mailing the ID and affidavit. I spoke to Nomsa Nthodi on the 7th of July 2017 enquiring about the documents and she told me that the process was in the final investigation. Till now I have not received any response from vodacom and the company keeps on debiting my account. I want vodacom to close this account and clear my name as I did not take up an contract with them.
