I seriously doubt they charged you $700 ETF, for 3 phones. I mean..sprint has a bad reception around where I live ( I only have it cause I get monthly discount
), I have had bad experience w/ them too. But when it comes to ETF they WILL CHARGE YOU $200 per phone. $200 even, no tax, total of $600 for 3. So theres something wrong here. Maybe they are charging your last bill.
