Unsuccessful porting

Initial contact was made about a month ago. I requested from the start that my existing number which is still post paid with Autopage but out of the two year contract period be ported to the new contract with Vodacom. This was confirmed and the application approved. I received the device about two weeks after that after i had to follow up numerous times. The device came with a micro sim although it requires a nano sim. They then sent me a nano sim after i notified them of the mistake. I tried to activate that sim stating again that it must be on my existing number. My current line did not disconnect as expected and after a few days i contacted the call center again to find out what was going on. It appeared that the activated that sim on a different number. I was the advised that they could not rectify it or send me a new sim and that i had to buy one at a vodashop, which i did. I am now trying for the third day to get this sim activated and porting my current number to it but even after speaking to a very reluctant supervisor there i am still not sorted. I am at my wits end. At this stage they can collect the device and i will get a different supplier.
