Can't Start The Pika Taxi Guy's Quest

As the title says it just won’t trigger,I got the VIP pass but he doesn’t say anything about the Quest,just the usual line… Anyone can help? I really can’t wait to lay my hands on Haxorite…

In the actual quest, you need access to Route 15 for one of its parts, so I assumed that you needed to reach route 15.

Gotta say, Mega Haxorus is a true beauty.
