CANCELLED DEBIT ORDER - BY WHO??????

Ok, so I've had a few proper issues with Vodacom during 2015 - crazy bill for data - but I did have a consultant at the end that was super friendly and so helpful!!! (Wish i could remember his name now), in a mail gave a huge thanks to him... Fix whatever it is that you guys are doing... I never cancelled my debit order, I simply asked what the process was to cancel it... In your e-mail, with your cancellation form (which i never filled in and sent to you), you told me (and I've still got all on e-mail) that i HAVE to fill the form in and send back to you for the accounts department to review before it'll be cancelled... NOW SOMEONE WENT AND CANCELLED MY DEBIT ORDER????? So I ask - who the hell gave permission for this to go through if i never completed the form and never sent it to you guys... I simply wanted to know what the process was... Now my account is in arrears??? Very disappointing! I have now made a payment to my account - pls don't debit it again on the 31st as per your \debit instruction when it will apparently be debited when you log in via mobile or web"Not happy with Vodacom right now... =("""
