STILL NO UPDATE OR CONTACT FROM MTN

So MTN still has not come back to me! and im really tired of having to chase them to sort out my Issue. Can anyone advise what i can do now to get my contract cancelled with Immediate effect?<br> <br> Find it so Strange that we as consumers in SA get this kind of treatment.<br> One thing i can say for certain is how consistent MTN is at administrating disgusting levels of service.<br> <br> Emails to complaints departments Ignored by MTN, Hello Peter complaints Ignored by MTN, facebook posts Ignored by MTN...<br> <br> Can anyone please assist with how i escalate to the ombudsman..
