I received a phone call yesterday from Art Boards. They have apologized for the quality of the block they sent me and have promised to refund the cost. I appreciate and admire that apology and I feel obligated to let you know of their apology. Mistakes can happen when building things and when restitution is offered for those mistakes it's time to move on.
I recognize now that if I hadn't invested so much time and effort working on that block, only to find the effort was wasted, I probably wouldn't have been so hasty to vent my spleen. So I apologize for jumping the gun and going "public" with this so soon.
