The way they are structured it may work even better 5/4, it is just a matter of time when they have to give in on that. Are you sure your message is passed on to the relevant Department or did the Agent took the buffer and just dropped it as they promised they can find Pilots for that crappy condition?.
Write to them directly and tell them, I am more then 100% on the side that eroding conditions should be stopped. Even when I was out of a Job I took not the first offer, was the lowest by the way, I took one who gave me more pleasure.
Fly safe and land happy
