Respected Sir,

I got a letter from Prime Financial Services (101 Golden Ave, Sydney NS, Canada B3L3C5) on July 22nd  2010  saying that I won a lottery of  $ 450,000. With this letter ,there was a check of $ 4,800 which had my name and address on it. The letter said that I have to contact the claims agent  Ann Smith @ 1778-323 3748. There by I contact this Person Ann smith at the 1778-323-3748 and I was asked to deposit this check ($4,800) to my bank account. Also I asked  to contact the same person when this money is available in my bank accoTD Bank Account . According to what she said , I deposited the check  to my account on July 26th . I again contact Ann smith and she said  I have to sent tax amount $ 3,860 to Two persons named  Louis Keith and  Joyce Sreeman at 222 West Ave Malaga Spain  Through Western Union.(each person $ 1930). 

On July 27th Money was available on my account. Then  I withdrew  $ 4,100  and I  sent money to Louis Keith and Joyce sreeman (1930 each person).She called me back after they received money and I was asked to sent $ 2,500 again to one of the above persons for insurance. I didnt send any money after that because I thought there is something wrong in this. When I checked my account on July 29th , I came to know that the check was alternated and the check was returned by the bank. Then I got a negative balance in my account $ - 4100.62.
