Complaint Review: Zenith Technologies

I applied for a part time job on craigs list. Then a Patrick Spencer contacted me via email as if was hired. He sent me information. Then later on he sent me a cashier's check of $2850.00 drawn on associated bank. I called the bank to verify funds. the bank said they were available. The funds were supposed to be for my start up at home business and for me to send the funds via western union to Ralph Hand in Philadelphia, PA. I deposited the check 11/12/09. It cleared my bank ( I thought) 11/13/09. I sent $2375.00 to the Ralph Hand as required. Monday 11/16/09. I had a hold on my account from my bank saying deposit hold. I went to western union to retrieve the funds. They wouldn't give it to me saying that i needed to call. I could have retrieved it because it wasn't picked up yet. I got busy at work & forgot.  I sent the email to western union but didn't call. They didn't email me til late Monday evening. I replied. I returned to work tuesday 11/17/09 & looked up the MTCN#. The funds were picked up. I did a search today & found the rip off report. I filed a claim with western union. I filed a police report. I am not sure if i have to pay these funds back. I should have known.
