Printroom.com not issuing photographers profit checks Santa Clara, California

Printroom is not issuing profit checks to photographers. They owe me a December 2010 check for over $250. Numerous contacts leave them promising to send it. The same song and dance as they have given every other photographer.
I have been with them for over 7 years, too bad as they used to give great service.
Now, like others, it has forced me to change service, remove my pics so they don't continue to sell them and keep all the $$.
Do not sign up with them. They don't keep their part of the contract.
I suspect they kept one of my checks last year, I can't find a record of it and they won't respond to inquiries for it.
