Deactivation of number

My contract was finished with vodacom and I requested to be moved over to prepaid as from 1 April. On 31 March my cell number stopped working and I have not been able to use my number since. I have spent hours on the phone with various deparments and have gone to sandton vodacom shop. I have been told so many different stories but it now seems my number was moved to the new \C 3d\" department and they need to activate my number. No one has assisted. It is shocking that even speaking to managers no one calls me back and I still don't have a phone"
