When this has happened to me, I have received emails and telephone calls. I really appreciate the fact that they took time to let me know that (a) the fabric was out of stock or (b) they didn't have as much of the fabric as I requested or (c) they have the fabric I want, in the amount I want, but it is in two pieces. I would never do business again with a company that cancelled my order, or a part of it, without telling me.
