Transcript for Tracking Too-Good-To-Be-True 'Free Vacation' Mail Offer

It's the promise of free airplane tickets arrived to your house tomorrow, you may think it was a holiday miracle. But we were skeptical, and decided to track them down. Guess what happened? Here's Rebecca Jarvis. Reporter: Tis the season for traveling. So, when tickets showed up in the mailbox, it may seem like holiday cheer. I'm just going to ask them a couple of questions. Tonight, we're on a mission to track the free vacation runaround. So, where it's the free trip? We got this note. Our then-executive producer received a letter congratulating him on a dream vacation. You will get two nights at a Marriott hotel. The value is up to $1,398. Sounds pretty good. Reporter: When we googled their phone number, we got this. Complaints. And it all goes to that phone number that we're about to call. So, we decided to schedule an appointment with this mystery company. I received a letter about some free tickets. Reporter: To claim our free trip. So, I come, stay for the presentation, I get two tickets. We sent two ABC news producers wearing hidden cameras to get the tickets. The location, in Brooklyn, new York. Good afternoon, how is everybody doing? All right, all right. Reporter: It starts with him congratulating everybody for being invited. This is a presentation about vacation and travel. Reporter: We find a relentless sales pitch that lasts more than 90 minutes. If this doesn't save you one nickel, then don't buy. But I think you will be impressed. Reporter: At the conclusion, they come in to close the deal on packages that cost thousands of dollars. We're not going to sign up. Sorry. Reporter: But that's not enough. They're moved to three different locations with three different sales people, each trying to get us to sign up. Congratulations, welcome aboard. Reporter: Two hours later, we're still empty-handed. We're eventually given these vouchers for a free trip. So far, it's only cost us two hours spent at the seminar. But there's more. We have to send in money to get the vouchers. That's not a trip. Well, it's an activation form to get more offers, asking for more money. Reporter: An activation form. That's right, 15 days later, we didn't get tickets, but instead a solicitation for more money. It's been about two months, now we've tracked them down in new Jersey, and we're going meet them and ask them a few questions. I understand they're in the basement right now preparing for the presentations. We're just going to go in and ask them a couple of questions. When we first walked in, we saw familiar faces from the first seminar. I'm Rebecca Jarvis with ABC news. We were left with this guy who calls himself Thorne. We were told we qualified for complimentary travel. Then asked to pay $150 for that. We did pay, but didn't get any complimentary travel. We were sent these. Is this a ticket? These are ser ticertificates -- Reporter: Is that my ticket? He dodges our questions and can't seem to explain why the free trip costs so much money. I'm not seeing any free tickets. Where are the complimentary tickets? I'll be forward with you. We give a 90-minute presentation. If you attended it, this is fine. Reporter: The company claims the gifts are fulfilled by an outside company. I'll be frank with you. That's what this say. Reporter: The New York attorney general says third-party companies are a sign of trouble. They make it hard by changing their names to track them down. Reporter: We sent them the money, got them. Then we were told to pay $59 a person. Which was identified -- Reporter: But that's not complimentary. You have to jump through hoops. Reporter: Correct. How many hoops do you jump through? You follow the instructions. Provided all instructions are followed. You got these. As long as you follow these individual instructions, you will receive two tickets for anywhere in the continental united STEs. Reporter: He or anyone else got back to us. We still don't have that hotel stay or tickets we were promised. Now, we've been offered a new deal. A new opportunity to do more business with this company. But still, no tickets or hotel. If someone is calling you up or e-mailing you with something that seems too good to be true, it's probably not true. Reporter: Rebecca Jarvis, for "Nightline," in New York.
