Contract not cancelled after end of term

I have three data contracts that had expired end of October. I have send the forms and Id via e-mail to ensure the contract stop as requested by MTN. Received a responds from them asking why I want to end it. I rep**** why and can you believe it money has been deducted of my account end of October for November. Only get automated response.<br> Struggling since May2015 to have my address changed. Been to Century city. E-mailed all documents but nothing changes.<br> Maybe I must report this to the Ombus man.
