AT&T store employee promised full trade-in value after inspecting phone but store did not honor it when I brought it back in
I decided to buy an iPhone 14 Pro after the AT&T store rep inspected my iPhone 12 mini and told me it was eligible for the full $700 trade-in promo currently running. When I finally brought the phone back the next day, I was told by another employee that I would only get $350. I would not have purchased the phone if I had been informed of this. I kept the trade-in and contacted the original rep who said he would look into it. I never heard back from him.
What recourse do I have at this point? If I can't get what I was promised, I would prefer to return the new phone and just switch carriers. Is this even an option anymore now that the line has been moved to the new phone? This whole experience feels like a classic bait and switch.
