MY number in a processing of being ported **********ly

Yesterday the 22/05/2019. I have received an sms saying my number is being ported. I called Vodacom to tell them I didn't request my number to be ported. I spoke to a consultant named Emma in porting department who refused to assist me cancelling the porting and refused to give me her surname saying they not allowed to give out their surnames. She said I must call mtn, that's where the number is ported to. Why should I call MTN I have a subscription with Vodacom not MTN. I was very upset, when they could not even do a simple thing. I told her that I am at risk. my banking could be accessed she said I must call the bank and cancel the cards. REALLY ??????????????????? How sad is that??
