I also subscribed to Sunset and I called their 800-number (800-784-6650) to be removed. Dial America answered and knew exactly what I was calling about. Very professional and apologetic and said I would be removed from being called by Sunset AND Dial America. As long as they don't call again, happy with their solution.
#1 - Everyone I spoke to regarding the call and message has been exceedingly polite and helpful.
Dial America left a message saying they would be calling back about my lapsed Sunset magazine subscription.
I gather that Dial America is 3rd party for many magazines to get subscriptions renewed.
If you take the call Dial America's outbound call center, they can remove you from the list.
Or you can call the Dial America inbound call center (800-784-6650) to be removed.
Without your Sunset subscriber # (above your name on the magazine), they may or may not be able to take you off the list
You can call Sunset directly at (800) 777 - 0117 and ask to be removed.
Again EVERYONE I spoke was polite and nice.
