Since the donation is a pledge from the professional, there is no binding contract requiring the professional to make the donation. It works on an honor system. To date, we have never had a professional not make their pledged donation after the transaction has closed. However, if you or one of your supporters finds out that a transaction has been completed through the program and the donation was never received, you may reach out and remind the professional of their pledge. If they refuse to make the donation at that point we will remove them from the Spark site.
