Toyota Sienna alignment emergency. Just got ripped off by Town Fair Tire and need a quick question answered;?

before I go cause a big problem at the shop. Please tell me where the front camber adjustment is. Technical answers will be understood. The guy told me he did an adjustment on my girlfriends car and I am very sure he did not. I am going back in 30 minutes to make his day in a bad way, but I need reurance regarding the method. Please help ASAP. I'm tired of mechanics ripping her off. Thanks.
