I did not receive a call from this number but my aunt received a letter stating she had won $250k and attached was a check for $4,970.  The letter is from Allstate Financial with a Canada address.  The check is from Life Investors Insurance Company.  I right away thought it was a scam so I started researching for any scams.  The first thing I did was to go the Allstate Financial website and tried to locate the "claims agent" named Anna Powells: 1-778-320-8099 and could not find her name in the site I also went to the Allstate Financial site in Canada and no luck.  The letter is signed by George Henderson also the name of Nancy Flores as a Tax Agent is on the letter.  This is really a scam.  Beware.

I did not recieve a call either, I  contacted the claims agent by the name of Andy Rodman.I spoke to this person and he explained that I had won 250,00.00 from a drawing through wal-mart,target,macys and home depot. The 4,975.63 was assist in paying canadian taxes on the money ,since I was not canadian. The check looked legit, but beware these guys are PROS

I too received a letter from this #788-320-8099 stating I won the canadian lottery.  I received a check for $4993.95 to help with the $4789.95 tax fee since I'm not canadian.  I called the number to check out if it was ligit.  The man (Mike Gibson) stated that the drawing was from wal-mart, target, macy's etc... and that I needed to deposit the check and then call them back and we could proceed.  I asked what information they were looking for and he just repeated the procedure I was to follow. Once I hung up I got online and looked up Great America Insurance out of Seattle, Wa and the only thing I found was insurance companies, then I looked up the check was written on Great American Life Insurance Company out of Cincinnati, OH  I called but the office was closed.  Then I looked up Carl H. Lindner whom they have as president.  Well he is ligit - he is the founder of Dole along with a hugh list of accomplishment which does include an Oh business Great American Life Insurance Company.  So I am going to call tomorrow and see if they know anything, then it's off to the post office to report the fraudulant scam.
