Telkom LTE network

I have 5 contracts with telkom, and we have been battling with data signal strength for the last few weeks. It is so bad that I had to purchase another network providor sim just to be able to use my phone, at my costs even though I pay for the telkom service. I have called them, everytime you get put through to a consultant that wants you to check the setting on your device, when the problem is the network and not the device. It is clear as daylight as all my devices are experiencing the same problem? How can all the devices have an issue? You try to explain this to the consultant but they do not listen. Its extremely frustrating. They tell you to move your router, how can a router that has been in the same losition for a year all of the sudden need moving to get signal? I would suggest anyone who is considering getting a telkom mobile LTE router to seriously reconsider it. BAD SERVICE
