Many Attempts to get service

I have been trying to cancel my line as I am moving and do not want to be charged for it any more. I have sent 2 requests from the website, and tried to phone 10210 a number of times. When phoning 10210, the voice prompts ask you for the reason for your call, and then the Telkom number that the call relates to, and supposedly routes you to the correct department. After holding for some time, someone finally answered, again asked for the reason for my call and the phone number, and then put me through to another department. <br> After another 10 minutes of holding, they disconnected the call!<br> Please can someone help me cancel the line
