Industry Threadworks Shirt Sale

I recently placed an order for 1000 shirts with a company in San Diego called Industry Threadworks and they messed up the entire order! For years I've sold only shirts printed with discharge printing, which gives the shirts a faded look and a soft feel. I ordered discharge printing again from Industry Threadworks, but when I went to pick up the shirts, they had all been printed using a method called Plastisol. This is the process that most shirts are printed with because it costs less, but the printing is done on top of the material. Ryan, the owner, called this a "relatively insignificant" error and refused to print the shirts I ordered or refund my money saying I got a "great deal!" Is it a "great deal" to save money on something you didn't order?

LEGAL NOTICE AND UPDATE:

I believe that Industry Threadworks knowingly and deceptively violated 15 U.S. Code § 70a of the Federal Trade Commission Act by mislabeling 1000 garments, an unfair method of competition and an unfair and deceptive act or practice in commerce under the Federal Trade Commission Act [15 U.S.C. 41 et seq.].

I filed a complaint with the Federal Trade Commision as I do not want to be in violation of any federal laws myself. For this reason, I am stopping sales of all garments printed by Industry Threadworks which may be in violation of federal trade laws pending an investigation.
