Cellphone contract problems and network issues

I cancelled my phone contract on the 22nd of December with Vodacom and requested that they migrate my number back to prepaid but who ever processed the cancellation ended up cancelling even my network access and now my number is off the network and now I have had no network / internet access for the past 8 days. The most frustrating thing is that I have called the call center about 30 times and now whenever I call the automated response is that I have reached my call center calling limit for the month and can only call again next month. Every Consultant that I have spoken to tells me something different regarding my network issue and that I have apparently been moved to a new 3D system which is making it difficult for them to assist me. So my question is am I now suppose to stay without a network connection( No emails, no internet access for the whole month). I am so annoyed and angry that I tried to port to another network (Cell C) and instead received a message from Vodacom telling me that they are declining my port, is that not my constitutional right to have freedom of choice because currently that has been taken away from me by Vodacom. <br> <br> Number in question is ***.
