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

This is exactlly what is happening to me. Has been Great ever since I have had it almost 2 years. Now for the past few weeks when I do a speed test on speedtest.net I am getting as low as 3 and as high as 6 download, but about 20 upload. If I connect a VPN I start getting almost 200 download again. The issue is watching YouTube TV the video is very distorted if I am not using a VPN. I have spoken with them and got the generic we will create a ticket. That was two weeks ago. I am at a loss for what to do. T-Mobile is about all I can get where I live, my other option is Ritter and they are DSL with a Max of 6 download and 1 Upload. I am getting faster speeds tethering my Visible phone to my GLI Router that I am with T-Mobile.
