Telkom service

I am with telkom about 15 years. I have a Fibre 20 Meg line with 20up and 20 down. My TV has been buffering foe that 4 months and been calling in every month so far. When I don't pay I get cut off, why should I pay for a business line by the way that is not working. I explain to one consultant that when I'm using 4 dives mubtv buffers, her response was when you want h TV turn off all other devices, like really, I canceled my account in canal walk and was sent a reference number and was guaranteed some one will call me within 7 working days it's been 14 or more and Ghostbusters is still calling. I eventually called in and was told they don't have any records of my cancelation and I have it on email. My last call l10 mons ago they could not pick me up on my ID or my VPN number to check my wifi connection. Why do I pay for a business line if I get **** service like really. When the world runs everything on internet and your service provider can't give you that service you pay for then what can you do right, fool. Telkom really now this is the 21at century get with the programme
