Terrible Service

I converted my contract line to prepaid, my cell phone has been inactive since the 31.03.2015 and I was told it will take 24 hours for the conversion to be complete. I called yesterday 4 times just to be told all wrong information from various - I had 4 different stories why my line is inactive, how is that possible!!! Eventually I spoke to Anna from the call centre who advised that the conversion will take 24 hours. This morning 01.04.2015 my phone is still inactive, I am unable to make calls send sms's and have no internet connection whatsoever!!! I spoke to Megan this morning who informed me that my line was only changed over at 14:24pm yesterday but they CANNOT tell me WHY my phone has been off since yesterday morning if the change was only done at 14:24pm!!!! and I am now getting excuses that the server has crashed...the service is pathetic, the staff cannot assist with queries or give you any feedback even if the server has crashed none of us were informed about this. The service from Vodacom seems to be getting worst. my phone is now inactive for more then 24 hours and no one can tell me why or assist, how is this possible for such a huge company???? Service is very very bad
