Worst service ever

I just received the worst service ever. Our landline and internet stopped working on Saturday. We reported it and once again we get the same lame excuse. According to them our cable has been ******. So now we go to the Telkom shop in Mall at Reds Centurion. At first they are too busy so we go do our shopping first. When we go back it is 6 minutes before closing time. I understand that they cannot finalise anything for me, but I only asked to check if we have coverage. Check on your phone was their answer. And while I try and explain that I do not have internet as my adsl line is not working, they just keep telling me to check on my phone. All I asked is just to tell me if we have coverage. It would have taken a few minutes. I am so tired of dealing with Telkom and never getting any service or straight answers.
