I have had good responses from companies when I complain in letter and use CC: to the magazines that review the specific product. So I would suggest you write a letter to the CEO/President, Quality Control Manager, etc,. (or all of the above) and tell them what THEIR problem is. Be respectful, tell them exactly what happened, and tell them what you want them to do.
Mention that you have already told the members of this Board and notified various quilting magazines of what has happened, and that we are ALL waiting to see how this problem is resolved. I bet you will have some new fabric and an apology in quick order.
