Hours cut because I couldn’t make it to my shift

So I had to call in to work because I was having issues with active homelessness, and when I called in my manager said I needed to find a replacement because they're my hours, I already looked it up and I plan on showing her today that it's management that need to do that, however she also said she would be cutting my hours for next week if I couldn't come in, I was just wondering if there's anything I can do, I live in new Mexico btw.
