Cancellation being ignored

Due to the sale of our home, a cancellation and suspension request was put through last week. According to the Telkom Direct Store, feedback will be given within 48-72 hours. I went through to the Telkom Direct Store Monday, since no feedback from last week was given. Another cancellation was done (This time I emailed the cancellations department as well). Almost 72 hours are gone again and still no feedback. No owners are moving in and the line is not yet suspended and cancelled. If the line is used, the bill comes to me. I will not pay anything that I didn't use. They can go to court, I will be there. Their service is nothing but appalling. The irony is I get a call to sell more products to me. I was thinking of using them again but Telkom seems to be a dead beat organisation. Its a sad state of affairs where customers spend hours at the Store and on the phone and still no feedback is given. Asked to escalate, people in the store can't or rather don't care.
