Western Union Financial Services,Inc Return's not honored. Englewood, Colorado

February 20,2013,i purchased a western union money order to buy products from another company,the company had sold out of the products i ordered.The company returned the uncashed money order back to me,and i took it to western union for reimbursement for my refund.The western union clerk told me,i would have to send it to their headquarters,and have it traced for lost or stolen,and wait (30) days before reimbursement,i showed the clerk my receipt of purchase, and returned money order to show it was not lost or stolen,then i was told western union did not honor their returned money orders unless i pay the ($15.00 to have it traced.How can you trace a returned money order?This is a Ripoff.
