Landline is dead

I have app**** for a new line, got the line and everything was fine (service and support) BUT I have done a number change more than 7 days ago and I have had not connection from then... I have logged several call and have done numerous attempts to make contact again but I cant not call the support center as my line is dead.<br> <br> I have terrible internet that disconnects about every 3-4 hours. If telkom does not sort out this issue I will move all my services to alternative SPs. ALSO if I get a bill in the post from Telkom, I will insist on a correction as I have had no service and No Service, No Pay is my motto.<br> <br> Telkom, call me immediately
