Account issues regarding *****

In October this year I forwarded an affidavit to Vodacom stating that someone had bought a handset using my personal details. I did not receive feedback and contacted the ***** centre. This was acknowledged and reversals was done on this account. I was promised this this issue was sorted. The ***** unit apparently contacted the Vodacom account section to rectify this ********** purchase . I have now received a statement indicating that I owe R889.01 for December. I have sent emails and contacted the account section and call centre and no one can assist in this query. I do not have access to a Vodacom handset and am repeatedly being told to contact the call centre on 082111 and the operators are not helpful to my appeal to assist in resolution. It is extremely frustrating to be informed that the internal units within Vodacom cannot contact each other to correct this ********** transaction . Can anyone actually assist to resolve this query?
