Moving from ADSL- LTE AND CANT GET ANYONE TO ACTIVATE THE LINE

I have been struggling with Telkom since the beginning of November. I called to log a fault on my line because our wifi was down. I was told that a technician would come and sort it out. I then waited 3 days and nothing. when I called in I was told that my line was now moved to LTE (THIS WITHOUT MY KNOWLEDGE) they router arrives and 5 days later im still trying to get the sim card activated, ive spoken t various managers who have said they will assist but to date im no closer. the managers are Tshidiso Hlatswayo and Bheki Shange. please can someone advise me on what I should do. I don't have dstv and rely on the wifi.
