Excessive Spam, Junk Mail from "geeksquad" email address?

Teresa_Cyrus : thank you for your insightful advice. There is most likely similar reply as this one, somewhere, regarding unsubscribe to spam/junk emails - many of these spammers are linking google search page to the unsubscribe at the bottom of their marketing emails,  making it an additional futility to attempt to unsubscribe to something that you personally did not subscribe to in the first place. 

Additionally, these geek-squad spams that have nothing to do with making a purchase at Best Buy need be brought to the attention of Best Buy.
