Absolutely shocking service

We ordered a line from telkom business in Dec 2014 and after numerous calls and two months of waiting it was finally installed on 16th Feb 2015.We were given a new number and on the 17th the line was fully active but on the 20th the line was completely dead, not even a dialing tone.So we have been sitting with a line that we have not really used in the month that we've had it.I have been calling telkom almost every day since the installation with no joy.This is completely unacceptable as this line is for business purposes and i am yet to use it as such.It is four months down the line since the start of our relationship with telkom and it has been nothing but problems from the get go but the characters i am allowed for this report is definitely not enough to explain the problems we've had from the start.It has been long enough we need this sorted immediately.I really hope you do not contact me for a customer satisfaction survey because i have nothing good to say.
