Vodacom debiting my account for a data SIM card that’s not working

I took a data sim only contract with Vodacom in May with account number I***-6. The SIM card was delivered but turned out the portable router I had wasn’t compatible and had to buy a home router, which I did yesterday but the SIM card is still not working, I’ve taken it out and put a different SIM card on the home router band it works but the contract sim is not working. I have been calling Vodacom customer care the whole day, still no assistance but Vodacom is debiting my account since June, yet I can’t use the allocated data, so much inconvenience. I was told by all consultants from Vodacom that the SIM card is active and has been network synced , yet I can’t use it. They also don’t know what should be the next steps
