Refusal to cancel the contract and *********** staff.

I have had a phone contract with Telkom for two years and never experienced any problems until I wanted to upgrade. I app**** for an upgrade online then I was sent aan sms stating that I still left with few days( date was stipulated) before I qualify for upgrade. Then when the date arrived I was called and asked for a router contract that was on promotion. The consultant processed everything and I waited for it. It never got delivered then I called to check what caused the delay and I was told it was not processed. I asked the consultant to assist she said I should call sales department. I did not call them then the other day I was called and asked if I was aware that I qualify for an upgrade then I said yes when I told him that I want router he said I can only upgrade a phone. Then I asked him to cancel the contract he rudely hanged up the phone. To cut the story short, Telkom consultants are refusing to assist me to cancel the contract. Different consultants tell me different process of canceling the service. TELKOM please stop debting I no longer want ur service. Your consultants are *********** and very rude.
