Cancel my telephone line

<p>I moved out of my studio flat about a year ago. Before moving i had arranged for my telephone line to be cancelled and i was told to fill in a cancelation form and send it through and it would take 30 dyas. I sent this form about 3 times before they cancelled the line which only happened 2 months after i moved out and they still expect me to pay for a phone line that was supposed to be cancelled 2 months prior. Now i have an outstanding balance and i refuse to pay as this was a mistake on thier side. To date nobody from Telkom has assisted me and i will never pay that outstanding balance.</p>
