Telkom is ***********!

I have phoned Telkom multiple times and asked them about my contract. I've contacted them on Facebook too, they assured me that I only have the 10gig (plus 500mb night surfer) deal with them. I have a received an invoice from Telkom about a sim card I don't even own: - ********** . I must pay R74.52 rands for it at the end of June. Why is Telkom doing this to me? Everytime I phone your call centre, I am told a different story. You continously distance yourself from Telkom Mondo. At the end of the day Telkom has access to my account. Why are you failing to protect your clients from *****ulence? Why do I have a contract with Telkom which Telkom caller centre operators and IT staff cannot seem to pick up? Why am I being charged for data I haven't used? Who has this sim card that I must pay for? I want my money back. I think eNCA and checkpoint must do some investigative journalism on your company.
