Shona Anderson Mission Management & Trust counterfit check passing Tucson, Arizona

I am an Avon representative. I was contacted originally via the Avon website by one Shona Anderson claiming to need a representative. I agreed to sell to her. She wanted to place a rather large order and I said I would need a certified check or money order because of the value of the order. She said that she would do that and that I should send the "remainder" of the check to a certain address (thamar david, 221 Heathrow Drive, Riverdale, GA 30274) and this person would deliver the order to her. She didn't give me an address but said she lived in Atlantic Beach FL. When I received a check for 2150 for a 500 dollar order the bells started ringing. The check was drawn on a business (Mission Management & Trust Co), not a certified check or money order. I was told by my local bank the check was a counterfeit check. It was sent. via UPS; the original p/u scan according to UPS was Forest Park GA. Her original e-mail was a yahoo account, this changed to a rocketmail account later in the series of transactions. All was done via my hotmail account, she never did give me a phone number or address for her in FL.
