Just send them a bill for the $15 - 20 your Ag Extension suggested.
Whether the pay or not, it shows you hold them responsible.
An extravagant bill or a sad letter has little chance of response.
Maybe a quick read, a laugh, and a chuck in the garbage.
You may never get a reply no matter what you do.
Some people have little to no consideration for others.
That's just how it is.
Send a bill for a reasonable amount, then forget about it.
