Not to take Toshiba or the service center in Guatemala's side, but I think you highlight what I would guess is the problem here, which is that when you felt like you were ripping someone off to be able to make such a return, there are many people who would in fact actually rip the store off if they could get away with it. I believe stores in the US have done a good job of putting mechanisms in place to help counter such scammers, but this is likely not true in many other countries. Thus, it's hard for the manufacturer to offer warranties in these other countries.

But that's just a guess, why else would they stop supporting a warranty in Guatemala (at least if their line is true that they actually removed the warranty for this country) other than they'd gotten ripped off there more than their bottom line could handle?
