How to deal with ATT for unfair ETF?
By using an unlock code (from ATT customer service), my phone gets locked permanently. I have talked with ATT multiple times, ATT refused to fix it.
Because this bad customer support, I disconnected this service, and asked to return the phone device to ATT. ATT didn't want to take the phone back, and added the ETF to my bill, which I don't think I should pay.
Any advice appreciated,
