Artie, after eight months it should be evident that waiting for your regulators to slide down a firepole and solve your personal problem is not working. Yes, I'm sure you have told the callers to stop, but only verbally. Find addresses for the publisher and/or its hired call center and send them a "cease communication" notice via USPS Certified with return card. Should even this be ignored, keep good notes and sue the call center for TCPA violations.
