A 10/16/2009 BBB alert warned of a new phishing e-mail posing as BBB complaint confirmation:

“Beware of Bogus Emails coming from complaintsmajdivision@complaints.bbb.org

Better Business Bureau is alerting consumers and businesses about a new phishing attack that resembles an e-mail confirmation claiming the recipient has filed a complaint with BBB about a business. The malicious e-mails first came to the attention of BBB on Thursday, October 15.

When consumers file a complaint with BBB about a business, they may often receive a confirmation e-mail and subsequent follow-up e-mails from BBB on the status of their complaint. The malicious phishing e-mail attack is designed to mimic a confirmation e-mail from BBB and includes the full name of the recipient and the name of the company they supposedly filed a complaint about.

According to reports to BBB, individuals who have received this e-mail have not actually filed a complaint with BBB but are, instead, employed by the business the e-mail claims they have filed a complaint about.”

I highly recommend you read the rest of the BBB information about this phishing e-mail scheme here which shows a sample of the letter and suggests what you should do about it.
