********** phone contract

I discovered that a contract was **********ly opened in my name.The call center advised me to complete an affidavit at the police station and submit it to ********** was done on the 6th of September 2017.I then emailed them a further 6 times to follow up.This ********** phone line is still being billed to me and the amounts charged in August/September/October have not been reversed.A lady did call me,sometime in September and again in October to tell me they still investigating which store opened this contract,which I found strange as the Vodacom store that I visited initially told me that the account was opened in KZN somewhere and even gave me the store ID.I am concerned that my legitimate phone contracts could get blocked/lines cut as it looks like my account is in arrears due to this ********** bill on my name.
