I bought a new phone from an AT&T store in 2020. Paid the phone off, it was hooked up to my fiancés number. It’s now 2023 and I have switched because my bill increased to much to find out that there is a 4th line on my account that I didn’t ask for, authorize, or know about until now. I switched my 3 lines to T-Mobile and 3 months later they bill me for $320 for this line that I didn’t know about. When I called in the rep literally chuckled and said “yeah, it’s a marketing tactic used by people in the store. We get a lot of calls because the stores messed up”. They offered $100 off the $320. I think it’s insane they would expect someone to pay for a line that was fraudulent in the first yplace. I work in sales and would never mislead someone for my own fortune. It’s shame’s. Shady sales people in their stores.
