being blamed for my mothers actions

Last week, me & my mother attended open house for the college I'll be attending next spring. I've told my parents that I need to stay on campus because i don't feel that our home environment is suitable for me to focus on school. My mom understands, however my dad has been flip floppy on the idea. During open house, my mom left & went to the bank to withdraw the housing application fee. She did this on her own & I didn't want her to leave me by myself in the first place. She also told me & I had also asked her & she confirmed that she would withdraw the money & pay for the application fee & then she would get paid on the following Monday & she would replace the money . She also told me that she told my dad this. Today, I wake up to a text from my dad yelling at me saying it's my fault that he doesn't have water in his apartment (he works out of state) & my brother who was supposed to leave with him today says that it's my fault & that I need to fix it . But it was my mom doing everything & she told me she would take care of it.
