Western Union…please help :(

I used Western Union to send money for a purchase I made. I got my MTCN from them, and I called their number and dialed the MTCN when asked. I just checked the status of my transfer on their website and got a message saying

"W0131 We do not have an order with the provided information. Please verify your information and click Check Status."

I typed the EXACT number I was given, but I still get this message. Does it take a certain amount of time until the system recognizes your MTCN or…

Western Union…please help :(
