RMCS contract ****

Good day My vodacom number was changed to contract without my consent, how this is even possible is beyond me. I have not had an edgars or Jet account for over 7 years yet they changed my number to contract now, this is ***** how is this happening without consulting with the person owning the phone. someone needs to get back to me urgently regarding this matter or i will take this even further as i did not give my consent to change my number to contract. And i will not pay for anything as i did not give my consent to change my number let me make that clear.
