Port existing number unavailable due to new system

I am trying to take out a new contract with Vodacom, keeping my existing Cell C number. My Cell C contract came to and end and is currently on pre-paid. The port was initiated in store on Tuesday 29/03/2016, but yesterday 30/03/2016, I was told due to a new system the port functionality is apparently unavailable.<br> <br> This is unacceptable. I did the exact same thing last year May 2015.<br> <br> Please guys, help me become a happy new Vodacom customer.
