AT&T offered an upgrade with no charge, but went ahead charged?
AT&T offered 1/2 price on a new phone, but only gave a credit of $10 per the life of contract of the phone. Don’t fall for 1/2 price phone deal. Also, when AT&T offered an upgrade without additional charges, don’t agree with AT&T because they charged you more in next billing. And these days due to Covid, if you wanted to talk to manager (AT&T requested a call back to you, but nobody called you back). When you asked AT&T looked into anybody from AT&T called you back, AT&T representative or manager couldn’t tell you if their people have called you or not. So at the end, you ended up with an increase in your bill from month to month without anyone from AT&T to look into your bill. Bottom line is nobody from AT&T wanted to help me to look into my bill with those extra charges.
