Well you would have to calculate the value of your time vs. either a) cost of attorneys (whose time is very expensive and it's a black box of costs) b) other things that you do that could be offloaded to someone else or perhaps c) putting someone of less value in charge of wasting of time.

We are not talking about hours and hours all at once either. We are talking about being a constant time waster and pain in the ass a little bit at a time or as much as possible while still flying under the radar and appearing not to be doing it on purpose (which you are).

At a certain point people will act in their self interest and perhaps give you what you want. At least that has been my experience when I've followed this path.
