Query: Worst Experience

I received this item only to discover the company had sent me a package of paper that was the wrong size, color, and brand. I called in to report this, and was told that the listing on amazon is a mistake and they do not actually have this item in stock, nor will they ever have this item in stock. This caused me to be late on a project costing me several hundred dollars. The customer service experience was miserable, with no sympathy, and when I asked to be transferred to a manager I was sent to a voice mail. No manager ever called me back. I was finally able to get a call back and get an adequate refund, but it no where near covers the financial loss I had from this company's mistake. DO NOT EVER ORDER FROM THEM>
