bait and switch - fraud - Leg Room Option Row 13 Seats B and C

J Q 191 GC to CHCH 22 08 2010 Had purchased extended leg room option in Row 13 B and C on this AB 320 flight, 5 and a half months prior to flying . At check in was advised that we had been switched to Row 1 D and E and told by the Jetstar Check In clerk that the leg room was the same. It is not. Jeststar sold an option for $54NZ that it did not deliver and their employees on the counter and the flight all lied about it. Will pursue this via consumer protection agencies.
