Vodacom cut off my sim

Vodacom decided to discontinue my simcard and give away my number while I was stuck overseas due to pandemic issues. I have had this number for 21 years and it is also my business contact number. ALL my contacts are on the sim, which I cannot access. How dare this happen without notification? I have tried to call vodqcom customer services, who couldn't assist and referred me to the useless Tobi bot. How do I discuss this with a robot? I want an investigation and my number back. This has cost my business severe losses. The number is ***.
