Telkom making it impossible to cancel service

My adsl and telephone line have not worked for a month, fault reported, nothing done. On 19th Feb, I filled in the cancellation request form - as instructed by your call centre - and emailed it to the cancellation department as requested with ID. I received an automated email saying someone would contact me within 72 hours to confirm. three weeks on - nothing. I've tried phoning but no-one can help. And my landline doesn't work so I'm left hanging for ages on a mobile at my own cost. This is ridiculous. <br> I want to cancel ! I am paying for a service that doesn't work! I also want a refund for the lack of service - again logged a dispute online and nothing.<br>
