Wedding booked Travel agency being really rude

I suggest you write to travel agent in a clear and businesslike way and get those tickets sorted to the correct spellings - their mistake - they must put it right!! A written reply is always worth the paper it's written on.

I can understand your frustration but hold your fire until you have correct tickets in your hand.

A friend of mine recently was on her way to New York for a family holiday. One childs name was incorrectly spelled (different to spelling on passport) and child was not allowed to travel. Whole family turned back at the Airport.
 

Sounds like you just caught the manager on a bad day, give him/her the benefit of the doubt and address your concerns via email/fax.
