How do i get US based support?

I used to talk to Idaho every time I called before 9 pm.  I have called at all kinds of hours trying to reach "my team".  I even went to the FB page.  I was waiting for 20 minutes in between apologies for FB.  I called 5 different times through the day trying to reach someone that speaks understandable English.  I have been a customer for nearly 2 decades.  I said I would never leave because of the customer service.  I will try one more time.  I'm at a point that all I have are 2 watches that I owe on.  All the phones are paid off and I just need someone to talk to me (I was calling about auto payments and upgrades). Went to the local T-Mobile store.  There are several people standing, no where to sit and someone else was waiting for over an hour to talk to someone.  I don't know if you've ever had to stand for several hours, your feet hurt.  I am so done, I'm paying my bill and switching to anyone else.
