Reaching a Generation

Almost one year ago now Reaching a Generation purchased a trailer from me in my personal capacity. They paid for it and went on their way, it wasn't until two weeks ago that they needed my help to register the trailer as they hadn't bothered to do so in January of this year! I happily helped as best I could, and was told I would be reimbursed for the costs thereof coming to only R560, meaning they would be able to collect without payment the license disc and all necessary documentation at their leisure. Lizzy has now one week later delayed payment to me. It doesn't seem as if they expect to pay me now that they have what they want. Not a great example they are setting as "Christian" people, as they know I cannot afford to have paid the bill for them, now needed to lend money to live as they promised to pay me back.
