Very poor customer service

Around June 2016 I received a call from Vodacom consultant verifying the contract I have with them. I told the lady I do not have a Vodacom contract and I never even had one previously, what she see might be as a results of ***** and she must cancel it immediately. she requested I send her an Affidavit disputing the account which I did but nothing has been done since then, I never heard anything from Vodacom and I just learned that the account is still in my name. This is annoying from a big company like Vodacom. I trust them no more.
