Contract cancelled

Dear Vodacom<br> <br> I cancelled my contract - Ref 001C8aBB1SAAVBAY.<br> <br> You guys cancelled my debit order - not me - but now your Subscriber Collections department is emailing me about arrears.<br> <br> My account was paid in full monthly by debit order so I do not understand why there are any arrears.<br> <br> Sorry but I will not be paying - I do not even live in South Africa anymore.<br> <br> Cheers<br> Megan
