No lte connection

I have had telkom broadband internet connection problems since the 3rd of Dec 2019. I currently run 2 lte modems and not one of them wants to connect me to the internet. The router is showing full bars but thats were it stops. My father and mother in law who stays a few blocks away have had the same issue with no internet the whole week also running 2 lte modems. I have phoned telkom and they mentioned to me to reset the router which i have done on numerous occasions even before i phoned and still no internet. They gave me a case number ********** 9 and that a technician will be coming out to assist in 24hrs but to no avail. The problem as i mentioned to them isnt with our routers or computer systems as i have had no issues for the last 4 years with the routers it is definitly something wrong with their tower but it seems to be falling on death ears. I need someone to assist me with this issue as i am a paying customer and will take my business somewhere else if not sorted out.
