Payment Alliance International, Inc Received check in mail to deposit in the amount of 3,519.59 Louisville , Kentucky

Today my wife and I received a check in the mail for the amount of $3,519.50 supposably written from an account for Plasticpak Packaging, Inc in Plymouth, MI.  It was accompanied with a letter from the Payment Alliance International, Inc company with the address of One Paragon Center 6060 Dutchmans Lane, Suite 320, Louisville, KY.  My wife telephoned the number on the letter that stated we were entitled to a sum of $100,000.00.  The check was to offset the tax amount for Non-British Residnt tax of $1,950.00 and they stated that we were supposed to deposit the check and call them back.  Instead we decided to telephone the Plasticpak Packaging company and they stated that they were extremely upset that someone was utilizing their name in a scam and that an FBI investigation has already been opened.  They provided the fax numbers so that we can fax the check and letter over to the authorities.  The real company Payment Alliance International posted the following on their website:  http://www.paymentallianceintl.com/About-Us/Contact-Us/Warning-Scam-using-PAI-Name
