So I mowed this guys lawn a few times and he owes me $72.00. It has been months since I have started sending him letters (some threatening to use a collecting agency). I have had no success. I am 16 years old so there is not much i can do in terms of knocking on his door and demanding to get paid (the guy is around 6'4 and 300 pounds lol) Are there any collecting agency's or something that would help me out even though it is such a small amount of money? I know that to most of you 72$ is pocket money, however to me it is decent money. Thanks!
