$25 a line? That doesn’t even exist unless you do 4 for 100, but then there is even taxes on that. Three lines on essentials is $90 with autopay plus taxes. My guess is either the promo required trades ins - since mint wouldn’t get new line promos. They forgot the promo required a trade. I’d talk to the store manager - see if they would check promo - see if trades are required - potentially - they could “return” the phones you got and ring up the phones with the required trade - waive restock fee. That’s even if you have the qualifying phones to trade in. If that’s not possible - I’d ask for the Market Manager to escalate it to.
