Worst network company I have ever dealt with!!!!!

Not happy with Vodacom at all!!!! I'm sick of the company. Some unknown person opened an account in my name in March of this year and i did everything Vodacom said i needed to do to remove this account against my name. i even have a reference number from ***** to say the account is *****ulent yet I'm receiving calls up to 5 times a day to say i owe on this *****ulent account. This has and is affecting my credit score as this is showing I'm in a arrears. i cannot keep calling everyday since March to sort this out.
