Telkom LTE down and call centre is of no help!!

I have several LTE packages from Telkom. Since Monday I haven't been able to connect to the internet at all. The modem switches to the blue 3G signal but has no connection. I even took one of my modems that I use at work and tried it at home. Out of three modems and two sim cards tried on 3 different computers/laptops I get the same result - NO INTERNET!! I phoned the call centre several times and get the same stupid replies...did you reset the modem? I tried three different modems on three different machines using two different sim cards...none of them work in that particular area. When I use my work modem at my business it works perfectly but it has no internet signal at my house. I keep asking them to check for a fault on the tower in my area at home but it is like talking to a brick wall. They have a "list" of answers given to them and can't think out of the box. IT IS NOT MY MODEM/S NOR MY SIM CARDS AND ALSO NOT MY COMPUTERS!!! CHECK THE TOWER, CHECK THE TOWER, CHECK THE TOWER!!!! Apparently they have to troubleshoot my hardware first before they can send someone to check the tower. Surely not all my modems, sim cards or computers can have a problem and work in one area and not in another. I have been using LTE at home for more than 3 years without any problems but now when there is a problem they are not willing to help. They don't care because I pay my account on time every month. As long as the money comes in who cares about the customer or customer service. Pathetic call centre help. No training and the people don't understand the industry they are employed in. Well done on upsetting yet another customer Telkom. BTW. I asked other people in my area and they have the same problem but Telkom insists that it must be a fault on my side...I don't know how their logic works.
