Frustrated with MTN online upgrade

<p>I have been contacted and informed that I qualufy for an upgrade. One of the options given to me was to have my phone delivered to me...they were very helpful at that time therefor I opted for the delivery..which ended up being the worst mistake of my life. I have been contacting summer mobile and MTN almost every second day and are being send from the one to the other, each one claiming the problem is not on their side. I even tried cancelling the upgrade which was just as ineffective ..same story.! MTN has no proble deducting the extra money from my account but seems unwilling to assist me in sorting this mess. If MTN knows the poor service exists in online upgrading why not remove this service or do their clients really mean this little to them?</p>
