AT&T Mobile too? Hot damn I had AT&T Internet for a few years and they REALLY screwed up. I started having intermittent signal issues where the reception would drop to less than 1megabit per second. They kept sending techs out who would look at their ipad and say the box in the neighborhood is showing a good signal and it MUST be all the 3D printers I have in my spare bedroom (not realizing that those printers don’t even have wifi connections lol).

Finally after a dozen techs all told me I was crazy, I switched to cable internet and when I unplugged my DSL AT&T modem, it turns out the phone cable was loose (poor crimp job by the AT&T install tech when they installed the unit a few years earlier) - if one single tech had physically unplugged my modem to test signal quality from my end they would have caught the issue - but nope. So I called AT&T to cancel and they refused to cancel - they transferred the call to an account retention specialist who kept refusing to let me cancel the service - trying to offer me better rates and such. I was shaking I so angry, I told them they had a dozen chances over six months to fix the issue and never did.
