SIM SWAP Bad Service

Hello everyone, My name is Bongumusa Msimango just want to share a SIM SWAP bad service I have received from MTN. I have lost my BB Z10 on the 29/04/2018 and I have bought another phone and tried to call in 173 for a sim swap request. unfortunately I couldn't remember and correctly answer security question but I was advanced by the call center agent to make SAPS Affidavit and certified ID copy to stating my case for the loss of my phone, that I am the right full owner of my number that I have used since 2013. Up until today 30/05/18 I haven't received my number back, even thou I have followed all the due process. I feel like MTN is taking my number and wanting to give it to somebody else.
