5G home internet keeps dropping

I have the same problem every three months or so. (I do not leave my hotspot plugged in, I turn it off when I'm done). I call T-Mobile, have to wait for a call back, then the CSR tries to be uber friendly without actually helping me, and I try not to get irritated because they obviously have no idea or ability to do anything - and when I finally get transferred to the tech queue, my call is dropped. So I have to start allll over again. Every three months.  Except tonight. Tonight I'm done. I can't get on the internet (thank god for my phone being a different provider). I called, got CSR'd, got dropped by the tech line, AGAIN. 

I'm tired of calling, tired of eventually being told "oh, a tower's down" - I'm going to have to look for another provider. I'm tired of getting this run around, when it's obvious they've bought up so many people's accounts (like Mint now) that they are probably exceeding capacity and so don't care if I leave after ten years. Fine.
