Abused by Vodacom

After around 8 months of battling to resolve my various issues, countless frustrating hours on the phone, visits to branches, I finally decided to end my contracts and to move onto pre-paid until I can port to MTN. Yesterday when I requested to port, Vodacom lived up to their useless reputation and declined my port. No reason supp**** - just a one liner message and to "Contact your service provider". When I call 082135 it tells me pre-paid customers cannot be supported via that number. So now I'm stuck between a rock and a hard place. The stores I go to can't help me. So after all the terrible, terrible, terrible service, they are now holding me ransom - I feel so abused by this disgusting company with their disgusting, useless service.
