Lame excuses because debit went off when it should not have

I was told that my last debit order would go off at the end of September because i cancelled my contract. Today my debit order went off again. I think this is utter bull****.

Today i phd though again n the lady said sorry it was wrong advice and that last debit order is October. But it wasnt only one consultant that confirmed end of sept because I phd plenty of times to make sure because i gave notice of cancellation in August . I have been a loyal client for years to Vodacom and to be treated like this is absolutely bull****. I told her i want the voice recording and she said no. Again its my right to have that recording where they confirmed that end September was my last debit order

I want a refund asap
