Frustration deluxe with telkom wifi

I am so fed up already. We have recently subscribed to a LTE deal with Telkom. Received the wi-fi router, all set up.... took me 2 hours to try and get everything sorted only to fail. Phone telkom the next day, held on for almost half an hour. Only to be told the sim card will take 24 to 48 hours to be activated and that I don't have to do anything. All fine and well, we wait 72 hours. I managed to get it set up after doing some searches myself on the net on how to reset wi-fi router online as it was still not working. Halleluya it was working.... only for us to come home today after being able to use it for one whole afternoon the day before only and there is no internet connection! All lights are lit up the right colour. Service is in order. Our devices connect fine but we can't do anything because it says no internet connection. Been holding on for the helpline for over an hour and have now run out of airtime..... over it!
