Telkom Mobile *****

Telkom activated a mobile contract in my name and I've been trying since 19 January 2019 to get it cancelled. Each month I get billed, I reverse the billing and now I've received a final written warning. I also found out I have several prepaid sims in my name. When I asked if this is ***** they said no, just an error. Yet I'm wasting time trying to get this contracts cancelled and for them to stop billing me. I await feedback from ***** department but am afraid that I won't get much joy. How do I get this issue resolved. Seems it's a common problem with Telkom!
