ODesk, now calling itself Upwork is a fraud. I sent them $200 to hold until I approved work submitted by a freelance artist. The artist took two months to work on a simple book cover and sent one unacceptable product. I sent the changes I wanted made. The freelancer did not make any changes and demanded payment. I sent a certified letter to Upwork stating that I rejected the product. They never signed for the letter. Upward sent two emails stating I must specifically reject the work or they would release the money on July 9. I replied to these emails on July 1 and again on July 6. On July 9th they sent a notice that they released the funds. There is no phone number to call this company, and their address in Mtn. View may not be real. They stole my deposit. Do not trust them. They are dishonest and their communication is nonexistent. I have also read that they don't pay their artists either.
