Say, you ordered a pack from a small business cottage manufacturer. Now suppose that almost two months after paying for the pack the small business hasn't seen fit to totally fill your order (your frame sheet and various other bits and pieces haven't been shipped). Now let's suppose the small business owner only responds to emails when he feels like it and doesn't have a phone number set up, so you can't really reach anyone to get this situation sorted out.
What are your options? More specifically how do you take legal action and make life miserable for the business owner?
