Cancel my account

I have ported my number and moved to cellc. All vodacom services has stoped working on the sim since last week. My cellc sim has been active and working since. All I want is to have my account cancelled with vodacom and to know how much I owe vodacom yet for the *********** staff you have its too hard for them to understand. It can't be everytime I call your systems are down. I was advised by dilion last week to call after the 5th but when I call to speak to him he refuses to take my call. I have left messages for him to call me back but he never gets back. I spent over 3 hours on the phone today yet nothing has been done. I keep going in circles from cancellations to the ports department. Your ports department has already confirmed the port has gone through,what the hold up.
