I do not want to speak to a bot!!

Yet again a *****ulent line was opened on my account. Vodacom handled it quickly and shut the account down, however I am still being billed for it. I am being harassed with text message urging me to pay my account. I tried to contact them which is impossible. After numerous calls I did manage to speak to an agent that gave me an email address to follow up. I emailed a few times without any response. I need the outstanding *****ulent amount removed from my account.
