It's so frustrating to have the start of a great project, and to have it all fall apart! My first quilt I did all the wrong things. I used stripes, which have to be perfect, flannel, which frays like crazy if you have to take it apart, and I didn't know how precise the 1/4 inch seams have to be. When the top was together, it was six inches longer on one side than the other. And it was just a small baby quilt! I took it to Hancock, and they basically said the same thing--your seams are all off, and you didn't use great fabric. Have a nice day. It was reqally frustrating. I went home, took it totally apart, redid the seams, and got it together. I ended up getting it finished in time for the birth of my first grandson. But I'm no longer a customer of theirs. Every goof is a learning experience, I guess. Hope yours gets figured out. Maybe if you take it apart and cut all the squares to a uniform size you can save it.
