Daughters dad is a ....

Advice is appreciated.. so my daughter who is 6, goes with her dad about every other weekend. It’s a custody order, so nothing I can do about it. Although I do encourage her to be with her dad, I feel it’s important. He’s just an ass#%*!.. anyway, every memorial weekend him and his family go to the beach, for several days and camp out or get a hotel, he’s got a trailer. So he tells me their leaving Friday.. he’s supposed to pick her up from school on fridays but he ask if I can get her and drop her off to him. That’s fine.. so I drop her off. I ask when their going to come back, she doesn’t have school Monday so he kind of just shrugs it off like “idk we’ll be back when we’re back” ok .. so I pick her up from school on Tuesday. She says they only went to the beach for one day and didn’t stay the night🤨hmmm.. ok.. I thought strange cause as long as I’ve known him, he’s always stayed many days. Then she says she has blisters on her hands, which she did, because she had to pull weeds to “earn going to the beach” her father told her🧐 wtf.. so she proceeds to tell me “ yeah we went to a one horse town🤷‍♀️(something her father must have said) and pulled weeds for two days cause daddy’s selling the house and we had to earn going to the beach”👿 so at this point I’m ready to cry, but I’m very cautious about how I act and the things I say in front of her. She has a sister who is also 6 only 6 months younger than her from a different woman obviously and an older brother who’s 17 also from a mother woman. So I ask did your sister and brother have to pulls weeds to? She says her sister did but her brother was at the beach with the grandma😠.. at this point I’m upset, not that she can tell. But I was hurt, all this time I’m thinking my baby was at the beach having fun and come to find out she’s somewhere else in the hot ass sun pulling weeds and raking/hoeing till her hands blister up!!!! Not to mention when I picked her up from school that Tuesday she had shoes 3 sizes to small for her and a long sleeve in 100 degree weather.. and I’m all for chores, but not like that! Now here’s the tricky part, if I mention any of this to him, he gets snarky, and will just keep telling me “k” over and over again no matter what I’m saying. He never cares what I have to say or how I feel about anything. He’s definitely a jerk to say the least. But I show him respect out of the love for my daughter. Am I overreacting on this? Should I say something to him even though he won’t care? Is it wrong? Is it right???? Idk.. he was a marine and is currently a sergeant for the police department. I feel like this affects his ability to be compassionate with his daughters sometimes. What to do, what to do???
