Very different experience with KYMCO Canada. Parts always seem to be available. Note that its normal that manufacturers don't talk to customers directly, its probably part of the contracts they have with dealerships, both sides have certain obligations and a manufacturer could obviously undercut their dealers, which wouldn't be right and would mean a lot of dealerships would be closing, so it's actually a good thing they didn't sell to you directly.
Call up the next closest dealer or whoever you bought the bike from.
