On monday my boss asked me if our client's website will be ready to launch on June.

We'd supposed to start the development last monday, but the client keeps asking for huge changes on the design, and the dedline continues the same.

Even worst:
The person asking for changes have no power for decisions, so very often our designers have to undo their work and turn back to a previous version just because that person forgot to ask their superior if he wants that change.
