SIM card only contract termination went bad

I recently switched from MTN to Vodacom 400 gigs data due to price increases at MTN. During my switching to Vodacom, I asked the business consultant that the Vodacom data does it have data share plan because I ported my number from MTN to Vodacom to be able to use the service. I asked her to show me how it is done and she said she is not sure how it is done but it is available services on Vodacom. The contract was signed on the 16 February 2026 and on the 17th I tried to data share which it was not possible to do after confirming with the Vodacom online. They told me to go back to the shop to cancel the contract before the grace period. Today I was told I need to pay Vodacom R3.8k for early termination and to my knowledge Vodacom business constultant failed to let me know that data share is not available for the SIM card only contract. Very disappointed. There is no way i would use hotspot to share data with my wife. The business consultant didn’t have a decency to say I was wrong to say that the data share is available. I want this contract terminated because it is not serving my requirements
