Telkom LTE constantly down past 2 months

I have been with Telkom LTE for 2 years. We have never had issues until the past 2 months. LTE constantly goes off completely for hours at a time. I cannot log a fault with Telkom because their call centre insiststs I must sit with them first and check things on the router. However where we stay, there is no Cell reception and I can only get LTE as an internet option in a router.

Our internet went off again last night, 27 September 2017 from 20h00 and is still off now. I tried explaining to the call centre that I am at work and need to log a fault. They were unable to help me and said there is no way of helping me unless I have the router in front of me.

I find this ridiculous. I cannot phone from home, I only have the LTE connection that works. How do I log a fault or get Telkom to do something and look into the problem. I still have 30Gigs to use this month and either Telkom must fix this or refund me for the data I cannot use.
