Today is 19 of January 2016 since that time my line has not function more than a week. I wish there was another telecommunications company but we are stuck with telkom and the worst service there is. I had 6 technicians at my house already. they come here check see my line is installed and tel me that the rest is not their work. so who's work is it to activate my line. how difficult can it be. My Brother in law stays with me in my house he also have a line. with no problems. I don't know what to do anymore. Telkom sends me a message the technician will come the days come it passes no technician. Today my line had a dial tone every now and then today i get home call telkom. my service has been discontinued. how can a service be discontinued if you never got it. Hellopeter help me please.
