Telkom are *******

I took a contract phone at Telkom. Fist time when they called me and offer the phone we agreed with everything we was spoke about one phone but when they deliver it. they bring two phone. The deal was one phone and two sim cards and they sad it's promotion . I took the phone. Then they started to deduct on my account and they took the amount that we were agreed. After 2 months I received a call from them they said I Owned them two months and the erias of 700r. I asked them why and the answered me and said I didn't pay for two months. I told them that no I payed than they've said I need to pay two phone not one. Ok we fight and fight until one of white lady call me and explain and open a case she followed it until she came back to me and told me they I'm right. She asked me what I want to do? Answer her I want to close this deal. Ok . She said she will sand a carrier guy to collect I said one of a phone is Bernet and my brother is from me so I will cancel buy I will pay for phone not a package of data and airtime she said it's ok. But they don't want block sim card and stop sanding a package
