I received an unsolicited email from "billing" (exposed email address is "firstname.lastname@example.org") telling me that they provide service through a link with Norton and that they billed my credit card for $299. Has anyone gotten anything like this. My guess is that this alleged vendor doesn't have my credit card number. Nothing in Norton support seems to address this issue. Even though I can dispute a charge like this (if it does show up on a credit card bill), I'd like to keep from getting such emails.
