I keep getting unwanted e-mails but because I didn't sign up to them I don't have the information I need to stop them at the source web site. they are becoming very aggravating with the number of e-mails numbering between 10-20 daily. I would prefer to keep account but need to know how to stop them coming through. because I have xbox live account and use this account for other game related stuff I have to close them aswell, obviously that would be a hassle. please can you offer a solution. i'm on windows 8.
