Cannot cancel Telkom landline

I've been trying to cancel my Landline for the last 5 days. The problem is when I log into my account it says 'no accounts available' so I cannot cancel my landline online. When I eventually, after 2 hours waiting, got to speak to a call centre agent, I explained everything to her, but was cut off without any help. My landline was out of order for the last week. I cannot afford to wait for 2 hours on my cell phone. I've also send numerous emails asking to cancel my landline. After 48 hours, still NO REPLY. Your service delivery really leaves a bitter taste in my mouth, never again will I opt to ever use your services again. All I want is for someone to contact me to assist me to cancel. Anyone that consider using TELKOM for anything, PLEASE DON'T!!!!!!!!!
