daughter hates going to her fathers!

My daughter absolutely hates going to her dads. She's never stayed longer than Friday to Sunday. He got her on the 16th and is keeping her til the 25th after he said he wasn't going to do that to her. He called me the Monday before saying he was taking her. He also said I could FaceTime her every day. I've asked every day since to talk to her and he ignores that. My daughter is going to ask why I didn't call or FaceTime her while she was gone. Is it wrong of me to tell her the truth that her dad said I could then would let me? Him and his mother are only doing this bc they think it hurts me. It does but it hurts my beautiful little girl more. He has a second baby with a young ass girl and she gets to talk to her daughter but I don't!
