T-Mobile Home Internet throttling speeds to certain servers (10x reduction)

I have been having a similar issue. Mine started during the NFC Championship game last Sunday. My Gateway doesn't just slow down it disconnects from the network altogether. After many frustrating hours on the phone with T Mobile people, including supervisors, I have no resolution. I finally found out they were doing "maintainance" on "my tower", which is just across the river from where I live. My service was spotty while the "maintainance" was being done. Once it was completed, the disconnecting and re-connecting every few minutes started. Admittedly, I use a big chunk of data every month as I am disabled and use Alexas and Ring products to run and protect my home. When my internet is out, I can't even turn my lights on! I have explained this to T Mobile reps and some have said they would prioritize my data, but it just continues to get worse. I think the worst thing about all of this is the lack of transparency. Customers who call in with this slow speed issue should be informed of what is REALLY going on so we can make informed comparisons and choices regarding which provider to use. This is the type of tactics that spawns class action lawsuits, especially when a customer asks point blank if his/her data is being slowed down by their company in any way. It is very disappointing! I had great service and they have decimated it! I have not tried a VPN yet but sounds like a good thing to try. I have connected my TV to my mobile hotspot, which connects to the same server(s) as my gateway, and my mobile hotspot connection is around 200 mbps at the same time the Gateway is constantly disconnecting/re-connecting to the same server. I rarely use any hotspot data (I get 40 gigs per month), so I am way under my high speed data threshold for that.
