No technicians attending to my LTE problem

I logged a problem with Telkom regarding my LTE reception and it has been established that they need to come and install an antenna to solve the problem. It has been 7 days of not being able to work as I do on-line teaching.<br> I phone 081180 3 times a day and they just can't get the help. I need to work to earn money and it is not possible and no one can help as the call centre can't contact the service division directly. My case reference is ***0.<br>
