Cell C contract

I've been trying to communicate with Cell C ***** unit from the 18th of April about a contract that was linked to my account without her knowledge. I've provided all the information the call center advised me to send but I have not received any communication from them. I've been paying for this contract from the 18/11/2021. I'm a pensioner I can't afford to waste money like this. Please help Cell C is deducting this money every month from her account. It shows that they don't care about their customer's if they fail to respond to the incidents reported.
