AT&T is sneaky and dishonest, they make their app and contact platform very unreliable, the same way they male you wait on the phone forever so you either put off cancellong, and fixing errors or cant get through to do it at all. I updated my app after checking my bill balance for the month and my bill went up over 20 dollars after the update was installed.. Explain that sneaky cheaters! AT&T... Ripping people off is their main objective.
