I too received "wonderful" news about a windfall. The check definitely appears real. However, I recently spoke to a clerk who also received a similar mailing. She asked her bank to hold it for her until she verified the information on the check. They deposited it. Now her bank wants her to pay for the returned check fee and the missing funds.
I was sad that she had been taken, but thought fraudulent checks can't possibly like that real.....Well these ones do! Beware. My check listed a "supposed" tax agent-Susan Edwards of Ottawa, Ontario, Canada K1P 6L5. However the company listed is out of Virginia.
I sent the fake check and the letter to this company. They are dealing with them.
