Disappointed Customer

I cancelled two contracts that were appearing on my bill without my acknowledgement and i was told that a ***** case is opened ant that the contracts were closed and won't appear on my statement but to date they still appear on my bill and i have never received any routers from telkom so i don't understand why i keep getting billed for something i don't use or never received and who authorized for me to get billed knowing that i never received any routers. I had to reverse payments due to the type of service that i am receiving and i am going to stop the payments because i am being over billed and my phone contract is now even suspended.
