Terrible just terrible and dont know what to do!

I have ADSL with telkom and my internet is constantly interrupted by the same issue either cable theft or a problem with a cable. Wouldnt fibre save telkom alot of money and alot of problems with cable theft? My internet has been off going on two weeks. My wife uses internet to work from home. I went to Telkom direct to get an intergrated sim so my wife can use that to work but the consultant says i can only get 2 gig even though i have a uncapped line at home. At this point i am desperate because my wife needs it. When i get home do the setup it says no internet access. I call telkom and they say its active and they dont know whats the problem and they will log a fault. Now i am sitting with adsl that dont work and an integrated sim that dont work. Where to from here? Do i go the LTE route than i only get 6megs download instead of 10meg? Any help
