To answer your question, they don't show the whole phone conversation. He was actually calling RossMAN for a good deal on a digital camera. He then threw in that bit about him changing things cuz he knew the machines/agents were listening since they also daylight as Hot Deal police that create $70 of $140 purchase coupons that you think exist but really don't. Then when you try to use them, all hell breaks loose and you end up not being able to shop there anymore. But there is a guy that lurks the HD forums, and he wants to be an informant of those trying to use these illegitimate coupons in hopes of being able to participate in all the HD's he wants to. But there is a Neo guy that acts sort of the BBB that tells them all how things are and how they should really be and that he is going to ensure the corrupt coupons aren't created to dupe us consumers. Meanwhile there is a person that can forsee upcoming deals and likes to make aware the potential savings to the masses.
Oh, and they have cool robots and flying ships too....
