Could an organisation be more chaotic

To have a small change made (to a booking they orginally messed up) it's taken me several days, around 20 emails, unreturned calls and no resolution to date. Each time a different consultant contacts me there is no history of my query and they are all saying different things and quoting different amounts. I'm told they will phone me but don't receive the call. I will never use this consultancy again and will certainly discourage anyone else from doing so.
