Narrative:

Location, ug 521 amida intersection. Climbing to FL330 on ug 521 when making position report over amida intersection, we reported passing through FL317 for FL330. Cenamer control advised us that we were cleared to cross amida at FL330. We never heard nor read back that clearance zoom climbed to FL330 and was level within 10 NM of amida.
