Either continue calling until you get your rick or chaulk up the $40 as a loss.... Cutting down his parents tree will not get you anything but trouble... They obviously have your number and could trace it back just as easily as you did and find out where you are and then seek legal action...
I had bratwurst boiled in a Kentucky Bourbon Barrel beer and it was magnificent... Only way it would have been better is if after the boiling, they were grilled, wrapped in bacon :D
