AT&T deceptive billing
Back in Nov 2020, I took AT&T up on their offer, trade in my iPhone XS with a credit of up to $700 on a new iPhone 12.
3 things I failed to notice:
1. They only credited me $245 and never paid it back to me or credit on my monthly bill
2. They (the company rep at a company store) changed my account to a 5 line account, giving me a reduced monthly rate - I failed to notice this. Now my rate has jumped to $45 a month per line (3)
3. My "monthly credit" of $26 a month for the new phone mysteriously stopped back in March; their customer service rep on the phone had no idea why.
