<human>: Give me a shortened version of the text

So I got a phone call from someone from a marketing group saying that they represent Virgin Group, Toshiba, Ford and United Airlines, and that I had won a chance to win one of four prizes: (1) A 32" HD Toshiba Flatscreen; (2) a Ford Escape; (3) A trip for Two; (4) $35,000. 

The only catch is that I have to come down to their office (in DC where I live/work) with my wife and wait for an "hour and 30 max" while 10-15 other "lucky couples" will also be drawing their prizes. There will be refreshments while we wait and listen to a "short ceremony thanking their sponsors," but I am "guaranteed to walk away with one of the four prizes." 
 
I asked how he got my information and he said that if I purchase products online or shop where I provided my information, then that's probably how they got it. I also asked who their sponsors were and they said Ford, Toshiba, United Airlines and Virgin Group

The questions:

* I asked if what he was doing was legal. He said yes. He can't lie, right?
* If it was telemarketing, then why not sell me something over the phone?
* If it's a timeshare thing, then why are they representing not-timeshare-ish companies?
* I'm sure there are other things I should be questioning, but I can't think of any at this moment. Anything I can call and ask?
* The guy's name was a typical American name, but he had a heavy Indian accent. Legit?
* Why not just give me my prize if I won something?
* He said ID or registering/signing anything was not necessary for anything was not necessary for claiming our prizes. Really?
<bot>: I got a call saying I won a chance to draw 1 of 4 actually cool prizes, but I have to go and claim it.
