Vodacom holding me hostage as a client contract ended but not allowing porting of number to MTN

<p>My contract ended with Vodacom in August.On<br />28th Nov I app**** to MTN for their Cyber deal and have my number ported but this request was rejected by Vodacom .Since the 30th of Nov I've phoned back and forth to Vodacom to try and find out the reason for the rejection.Consultants had told me it was due to R2.46 outstanding on my account , so I did an EFT for R5 just to make certain .Mtn tried to import my number again on 6th Dec and again Vodacom rejectedd it. This time got through to cancellations only to find out I need to give them 30days notice to change to pre paid and then it can be imported.This is ridiculous I'm the customer , my contract ended and because I wanna leave, I need to wait 30days ? I spoke to the manager at cancellations and he said there was nothing I could do to move across networks earlier.I don't wanna be a customer of vodacom I fulfilled my contract terms but I'm being held hostage by the vodacom network .How is this possible ...is Vodacom not ashamed of forcing customers to stay with them against their will.I thought the porting law allowed for freedom of choice once your contract is complete...is there any association I can lodge a complaint with?</p>
