WIFI Calling Preferences Being Forced to Cellular Preferred

Same issue for a long time.  I grabbed a screen shot the last time of the notification which says "WiFi calling preferences were auto updated..."  The key word there is auto.  I believe they periodically and automatically push down the change.  There has to be an advantage for them.

  I've called many times always having to go up 2 levels.  They deny it is happening nor that they have ever heard of it.  One time I talked to a tech that was quitting and he said his own phone does it and he couldn't get it resolved.

This needs to go to a class action law suit.  TMo has no right to change your phone settings.

I expect I will be leaving them as well.  What are our choices? I need a reliable phone.
