Debit order has not been stopped

I logged a complaint on the Vodacom website yesterday. It stated I would be contacted within 24 hours. Nothing had happened. So I decided to call the call centre today.<br> <br> I cancelled my contract which was on prepared in October 2015.<br> I only noticed this month that the money was still being debited off my account.<br> When I called in today to find out what was wrong. I was told that I was on the new system and can only be helped by someone else. I then sat on hold for 20 mins. After which I just hung up.<br> All I want is to stop these Debit orders from my account and to be reimbursed for the last 4 months, as I have not be using this data card since then.<br>
