Telkom providing bad/non existing service

We have logged a complaint on the 8th of February concerning our land line That's out of order, we have not had a response or feedback from Telkom yet, we use our airtime to try and contact them, but its nearly impossible to get a hold of an actual person after holding the line for more than half an hour, we logged a automated complaint that you can only log once, and when you log onto their website it simply says "complaint in progress", this is unacceptable, we have lost some of the things we have organized due to people not being able to get a hold of us!
