CHARGED ME PENALTIES FOR A CONTRACT I NEVER TOOK

I took out a contract from Telkom in November last year. They made a mistake and billed me for a second contract, which I had never seen nor signed for. After I fought to get that contract removed, Telkom then charged me a R7669 cancellation fee, which they refuse to correct. <br> <br> I have called customer service and spoken to countless team leaders in the billing/contracting department and NO-ONE will help me! They all claim to look into and NO FEEDBACK. <br> <br> Could someone please please help me, I'm not sure what else to do
