Telkom more like hellkom

After waiting 3 weeks for my telkom land line to be installed,I gave the the lady at the contact centre an instruction to notify me an hour before the installer came to my home to install line.This did not happen as I had to Neibour having to call me to notify me that telkom was a my residence.So I had to rush off from work at short notice to let him into my residance to install land line.After about an hour the technician said he was done with the installation but there was a big buzz on the line,which he could not resolve and he would hand call back to resolve the next day by another dep,this did not happen.as when I called the help desk they said that there is no such feedback and I had to log a new fault.So 2nd day of being with telkom and I'm logging calls and being billed for a faulty line.almost 2 weeks later and still no resolution.whats worse is that 3 days ago my land line goes completely dead.Cant make,receive calls and not Internet .Called the call centre from my cell phone,sat on hold for 25min only to have my call dropped.Seriously telkom.So now I'm sitting with no landline and no internet and no way of getting hold of telkom
