MTN ported my number without my knowledge and consent (this is *****)

I am so frustrated with MTN right now, I use Vodacom Network and I have been using my number for the past 18 years so yesterday MTN decided to port my Vodacom number over to them without my consent, I never requested my number to be ported over to MTN. I called MTN porting department this morning at 08:45 to find out how this was done without my knowledge and consent and Lindi the consultant told me that they do not port numbers over the phone and this porting might have been done online or via sms request and I was told that they are unable to trace who did the port. The consultant informed me that they will reverse the port within 2 hours and I will be reverted back to Vodacom and I will be able to use my number again but is has been 5 hours and my phone still says no network coverage, this is sooo frustrating as I AM UNABLE TO MAKE OR RECEIVE CALLS, this is such an inconvenience and MTN did not seem bothered by my grievance as this might be ********** and the consultant said there is nothing they can do about it. I did not cause this problem I need my number back at Vodacom and activated now!!!!
