Port without my Consent!!!!!!!!!!11

My phone stopped working Wednesday and I thought nothing of it. On Thursday I tried to make a call and my account was Suspended. I called Vodacom Friday and was instructed my number had been PORTED, without my consent mind you! I then went to a store and they informed me my number was ported to MTN. After going to MTN they indeed confirmed my number had been ported! We called the number and a lady called Tshidi answered the phone. I went back to Vodacom and asked how they PORTED THE NUMBER WITHOUT MY CONSENT!! I received no SMS from them asking to confirm Port!!! The Vodacom Store nor the Vodacom Call Centre could answer how my number was ported without my consent. All my business contacts use that number!
