I am so sorry this happened to you. Been there with my very first quilt. That's why I ended up getting my own longarm. You won't be happy with this quilt until you rip it out - I wouldn't be happy either! - so check out youtube for videos on skinning a quilt so you can do it quickly, easily and without ripping the quilt.
Also, I know this is hard, but the quilter needs to know that she really messed up on your quilt and that you are so unhappy with the quilting that you are ripping it all out. Unless she knows where she mess up, how can she improve? I know it seams a no-brainer, but some quilters think that tucks are all right (yeah, I know one and she quilts for other folks, but doesn't understand why no one ever gives her a second quilt to do for them).
