***** - Deduction after cancellation

I went into a Vodacom store on 5 august 2017 to cancel my vodacom account and debit order. The lady told me My account would be cancelled at end of august and the last debit order would come off my bank account at end of September 2017. It's now November and vodacom are still direct debiting my South African bank account. This is ***** . I no longer live in South Africa so I can't just phone or revisit the vodacom shop to resolve this.
