Need Advice!!! Reporting a daycare teacher

Jordyn`s Mom
My daughter just turned 3 in May, she was doing well with potty training in daycare, and  all of a sudden, the daycare started to tell me more often that she's out of diapers, so I didn't think much of it, and I brought diapers whenever needed. And about a week ago, I picked her up, and she was squatting by the bathroom, and when we got in the car I smelled that she pooped on herself, the day after she got in the car, and again she had pooped on herself, and a few times after, her diaper was sagging, filled with pee and I always pick her up after the class goes to the bathroom at 4. I spoke to the director about it yesterday, and today I tried to speak with the teacher, but she got an attitude and said that she wouldn't talk to me. So when I got home, I took a picture of the diaper, and I know it's the same diaper from 7 this morning when I dropped her off, because I use two different brands, Luvs for daycare, and parent choice for home. I never let my kids diapers get full to the point of sagging, so I'm ready to report this teacher. So I'm asking, does this diaper look too full, considering it had only been 30mins since I picked her up, and she supposedly sat on the potty at 4. I took a picture of it in front of the clock, to show the daycare director. Thanks ladies
