Still waiting for phone lines to work!!!!!!

I work for a specialist surgeon that is incredibly busy and my job relies on the use of not only my email, but also the phone lines as I am on the phone to the medical aids. However, I reported a problem with our lines 3 weeks ago! Each time a technician comes out, (when they eventually arrive as they take their time in responding) they blame the problem on LCS Samsung but when the Samsung techs come out, they test their phones and the problem does not lie there. What Telkom does not understand is that this isn't a personal line that can be down for weeks on end, we are dealing with people's lives and in many cases it is a literal life or death situation!<br> We cannot work like this anymore so I have resorted to Hello Peter in hope of getting some sort of a reaction out of Telkom!
