I have been receiving emails from a destiny hall claiming she works for Coors after I indicated I was interested in putting a decal on my car before I agreed to see the design,and before she sent any moneybut i told her I was no longer interested,and wouldn't respond to my emails after she wanted to send me money,which I later returned to her in the same self addressed envelope which I refused,and which was sent back refused by the post office.she also wanted me,after I got the money to send a check to a third party to pay for the design,and at that point,I realized it was a scam to get my financial information and refused to go through it as I told her I only wanted to deal with Coors and nobody else.now she is sending me threatening emails about contacting the FBI,and the CIA.I will be forwarding the email to my attorney and the federal trade commision.does she even work for Coors?
