Professional spammers disguised as a marketing company

Anydata is nothing more than a bunch of professional spammers. I own a beauty school and I keep getting engineering related emails from Essentra Components - these emails are sent out by Anydata despite the fact that my email addresses have been added to the national opt out registry. I have complained to Essentra Components numerous times and my name has still not been removed from their mailing list. I have tried blocking them emails, but then Anydata just sends them from a different email address. When Essentra asked me to send samples of the unsolicited emails to their Marketing Director, the emails bounced back because their own servers rejected the emails as spam. Where did you buy my contact information from? Why are you sending me irrelevant, unsolicited junk that I NEVER signed up for. Just take me off your database!!
