Activate my prepaid number

I requested vodacom to convert my number from contract to prepaid on the 11th January, instead they blocked my 12 years sim card. I reported the matter to vodacom and my number is still blocked. I went to vodacom store at sunny park, they sent the technicians email but still they haven't unblocked my number. At first they said Claris is busy with my case, on monday I went again to the store, the consultant called them they told him that Albertina is dealing with my case. My life is stuck I have no access to anything since they blocked my phone with airtime without my consent. It's been 13 days without a phone.
