The phone numbers (207) 622-5026, (207) 622-5028, (207) 623-3060, (207) 622-5031 (and probably a host of others) are all associated with a website called cheaptrips.com. I checked out the website and it looks to be a clearinghouse for the travel industry. If you're receiving calls from this company you've probably booked with a travel agency that doesn't have a "no sell" policy for their phone list.
