Vodacom please help me

I need help please, Vodacom is not helping me 😭😭😭😭. Some did a SIM swap last night with my Vodacom number, I called Vodacom many times with my phone not going through. I opted for tobi and it was not helping. Since this morning I was asking people to help me to go to the store for me however I was told they can't help me because I need to call but when I call +*** I am not going through. Now the person activated WhatsApp with my number and God knows what will happen next. I asked Vodacom to call me on an international number but they refused. I need help before anything happens to me and people around me. I can only give them my contact number if they can respond because my Vodacom number is taken by a stranger
