Absolutely no resolution after two months!

I had requested the installation of a landline and ADSL, and had told telkom that I work in PTA so arrangements would have to made prior to the date so I would be in Sandton at the time. They call me an hour before to say that they would be there so I had to leave work and go home especially. Then, I was not able to make calls and only receive as I was not authorised to make calls. This has been reported more than 6 times and everyone says that they would unblock it and ABSOLUTELY NOTHING!! The only number I can call is Telkom and believe me, I never want to speak to you again!!! This is absolutely pathetic service and no one seems to care. I don't get the point of this huge promotions that telkom is running whilst they can not resolve simple issues like removing blocks which only maybe God can explain why are there in the first place. I am so sick of having to deal with inefficient service at this company. Can someone please do something
