CANCEL MY CONTRACT!!!!!

I cancelled my contract with all the notice periods ( damn does make this difficult as possible ) and ported my number to Vodacom at the end of Aug 2015.<br> <br> How can MTN still on their system have my contract as active ?<br> <br> How can MTN send me a monthly account and take the money from my account !!!!<br> <br> To ask for assistance from the Help Desk and a non functional Retention Department solved nothing the past 2 weeks<br> <br> Is MTN just so not interested in their clients...<br> <br> I WANT MY MONEY BACK!!!!!!
