Bad Service with new Contract

I app**** online and received my new contract and Sim the 14th of July. and when I contacted the call centre was told that I can not port my existing number to my MTN contract. I was not told this when I app****. This contract is now actually useless to me. I than tried to activate the sim issued to me, but got an error, RICA barred. I was told to go to a MTN branch. After 3 trips and phone calls to call centre, I was finally told tolday at the branch that I can do a sim swap, BUT I have to pay R116 for the new SIM.

THIS IS CRAZY!!! I did not ask for a SIM, the one sent to me was faulty,

This is my first contract with MTN and 1 week into a 36 month contract and I am having issues. I please need this sorted ASAP.
