explorers Pikachu Recruit Help...

[WolfHybrid23]

I've been trying to recruit a pikachu as my game is severly broken (as it would seem; doing mission that are supposed to make the client join, they wont join and I don't get any rank points or poke for the mission complete) I've been searching Amp Plains and Far Amp Plains in the floors that it told me to search but I haven't encountered a single pikachu only Flaaphy and Electrobuzz. I have completed the story and the after store, I have also done the part where you explore Agis Cave with team charm and I have reached the point where the starter pokemon are able to evolve. Why arnt pikachus showing up, Its really frustrating especially sense I have to keep shutting of my DS every time I make it to the Amp Plains Clearing (Because ever sense I beat the boss there every time I reach the place the screen goes black and the music starts glitching and thats all that happens) Also I have requested a new game from gamestop several times and they keep telling me that "you don't have a warrant so anything like this is something you'll have to deal with or either buy a new game."
