Debit order still going off after cancellation?

<p>I cancelled my contract with Vodacom at the beginning of November and paid in full to cancel both my lines with them. Since then i ported to MTN and to my surprise i still have a Vodacom debit order going off on my account. I was assured that my account was cancelled and yet i still have money being removed from my account? Are you kidding me? This is poor business practice and now i have to phone Vodacom just sort "THEIR" mess out. This is appaling , and appaling is being nice >.<</p>
