Can't get expired contract to prepaid!!!

I have not been able to speak to anyone at the 808 call centre for a week, despite calling at least 10 times and often holding for 20 to 30 mins.<br> <br> On Tuesday 30 June 2015, I visited my local MTN shop in Mall @ Redds and they helped me to fill in a cancellation form and said it would take a couple of days due to the strike.<br> <br> Because I could still not reach the call centre, I again visited the above mentioned shop, only to be told that they have a huge backlog of cancellations.<br> <br> This is unacceptable! I need to have my number converted to prepaid so that I can port to Vodacom. This is holding up the whole process. <br> <br> What is my way forward??
