Porting of Vodacom number

My cell number was ported from Vodacom to MTN without my concent. I can't understand how is that possible. What is the use of RICA your sim card. I phoned Vodacom and they told me I have to phone MTN to reverse the process again, which I did. MTN told me it will be fixed in 2 hours. 4 Hours later it was still not fixed on which I phoned MTN again and the told me it was send to Vodacom and they have to activate it on their side. I phoned vodacom and asked them to please activate it. The consultant told me to remove my sim card and just put it back in the phone the following morning. This morning my sim is still not working. I phoned Vodacom again and by that time I was really annoyed already. I spoke to Tebogo of customer care and I told him the whole story again. And I told him I did not request for the port on which he rep**** he didn't ask for it aswell. I would like to know how does it happen that a number gets ported without the owners concent. That shows that no ones number is safe with Vodacom. According to them it's the first time that such a thing happened. I can't believe that. Because of their carelessness I have to make all these calls to get it fixed. I would like compesation for this mess that was made. I have been a vodacom customer from day one, but this made me change my mind. They can't be trusted anymore. I just want my number back and then will go to another capable network.
