I felt that way too after leaving spectrum att really fucked me good. They changed over the years & weren't like this. Now I switched to tmobile 25 a month whoohooo but even t-mobile sketchy as fuck.
I had to call my first day after switching because the associate who switched me over didn't enroll me in autopay like I asked him to when I was standing there & put insurance on my phone that I brought over which was already cracked. I had to be on the phone with customer service & deal with their bs too. ButnI got it all fixed after hours.
