HFL Dr Sam Robbins (HFL) HFL Solutions apparently sold my email address to spammers Las Vegas Nevada

After ordering some of their products online I saw a four-fold or greater increase in the amount of spam going to the email address I supplied them. My other email addresses saw no change and after using the affected one for ten years or so, I'm familiar enough with it to know what to expect. Either they are working with spammers, one of their employees is selling lists of customer's email addresses, or their customer database is not sufficiently secure and has been accessed by spammers.

I have communicated with the company twice about this. They have told me to be patient, but nothing has changed.
