Vodacom, your so called customer care is non existent!

About two years ago I phoned to cancel my data contract, I was told do so telephonically. The agent said my contract was cancelled. Great. So I go call to work overseas and months later notice that Vodacom is still deducting an amount from my bank account but a lesser amount than what I use to pay. I a not going to make international calls! So when I returned to SA I went into a Vodacom shop and when entering my ID number, the agent said they have nothing under my ID. Off I go to my bank, where I was told it’s definitely Vodacom but then the bank cancelled my debit order for Vodacom. Then all went quiet, I received no word from Vodacom and neither did I contact them as I was overseas again. Fast forward to two weeks ago and I am receiving emails from legal representatives for an amount of R174 in arrears! I told them according to my records Vodacom owes me more than that actually! Then I am instructed to go to a Vodacom shop to request all documentation in order to proof that I asked for this service to be cancelled!!! I go to a Vodacom shop and the agent there tells me they cannot provide me with such things and that I have to phone. Well I prefer to email as a phone call got me into this mess in the first place. Send an email to customer care. No more emails, only phone calls. In the meantime I am still being threatened by these legal representatives. I am absolutely stunned. I never received any messages from Vodacom although according to the legal people Vodacom tried to reach out to me so many times. Vodacom will never see me again.
