Poor Customer service

I want to expose Vodacom poor service especially in ***** department. I'm currently dealing with one of their *********** agents who keep asking me for reference or id number which was provided and attached to the escalation. It's been over 2 weeks now and my ***** matter hasn't been resolved. The name of the agent is Tanya and she seems clueless to me. I need some senior intervention since I'm not getting any resolution from their agents. Someone opened account using my details and I've warned them to cancel everything since it was not me, they went on to debit my account just ignoring my request. I keep calling them and I'm not winning. ***
