Step 1: Signed up for the FTC Do Not Call List.
Step 2: Received unsolicited commercial sales calls.
Step 3: Sent demand letter for violations of federal law. Minimum statutory penalty is $500 per violation which can be trebled to $1500 for willful violations. Unless there is a misdial violations are generally willful.
I asked for the minimum penalty of $1000. They provided some behind the scenes information I found useful about how telemarketing companies try to evade the law and we settled on $750.
Step 4: Received my check.
Marketing lesson of the day: pay attention to those FTC rules in your marketing.
