VODACOM SIM SWAP I DID NOT REQUEST, PHONE BLOCKED

I HAVE RECEIVED A CALL FROM VODACOM THIS MORNING TELLING ME THAT SOMEONE CALLED VODACOM AND REQUESTED A SIM SWAP FROM MY NUMBER ***, AND THEY CALLED ME AND CONFIRMED WITH ME AND I TOLD THEM THAT I HAVE NOT REQUESTED A SIM SWAP, AND I TOLD THEM THAT I DID NOT REQUEST A SIM SWAP, BUT NOW MY PHONE IS BLOCKED AND THE PERSON THAT CALLED FOR A SIM SWAP NOW HAS AN EXCESS TO MY NUMBER AND NOW MY LINE HAS BEEN BLOCKED. I NEED VODACOM TO BLOCK THIS PERSON AS WELL AND THEY MUST NOT RECEIVED CALLS AS WELL LIKE ME, AS I WILL GO A DO A SIM SWAP SINCE THIS IS MY NUMBER, AND I AM USING THIS NUMBER WORK AND ALL PERSONAL THINGS AND I AM EXPECTING AN IMPORTANT CALL AS I SPEAK NOW.
