Appalling Telkom service

i have always had terrible experiences with telkom, from connection of my landline to all through the duration of my time with them. your call their service team and you are either told you in the wrong department or their systems are being upgraded!! spent countless hours on the phone spending additional money and still no resolve. The freshest hell that i am now experiencing is a billing dispute and cancellation of my phone line. Billing dispute was logged in august already and still no response from them. Call in to services and they can offer no resolve, in the meantime they have continued to double bill me with no End in sight. Cancellation of my line was submitted in September and now its been a month later and still no feedback received. They have multiple channels that can be used to "assist" and yet none of them are reachable, or able to assist. I have never in my life encountered service this poor in my entire life and i am fed up with it.
