Debit going off month later even after settlement

Can someone please assist as I am unable to get through to the cancellations department and response on email takes way to long from vodacom. Customer care is also not able to assist as they even can't get through to cancellations. Last night another Debit order went off (R259.24) even after settling my contract at the end of February. How can I still be debited if I am not a customer of vodacom and my contract is settled? Can someone please explain and assist? Email have been sent To: [Email Removed] Customer care's systems is down and even they cant get through to Cancellations. Hello peter is my last resort as none of the vodacom channels is able to assist.
