I have no Internet!!!!!

For the last week I've been having massive issues with internet to a point where my modem says "no internet". But the last 2 days have been the worst.

1. I call your call centre, I'm told I'm being changed to another tower that is 2km away because the one I usually use has been down for more than a week. I'm told to give it an hour to register. I do, and the result? No internet connectivity the whole day 2. I call again, I'm told a technician will contact me coz all the trouble shooting is not helping. Did the technician ever call or come to my house....NO 3. So I call again today - I run a small business, haven't worked in 2 days, and periodically in the last week, I'm losing money. I spend 30 minutes with someone and they tell me to change the setting and use 5G NSA or something like that. I tell him I've done that, but now I have zero network, the screen is not even registering it's blank. He puts me on hold and says he is trying to figure it out - 15 minutes later my airtime runs out, and he doesn't call me back to fix the issue.
