Personally, I will never call you again if I don't get that dime back. However, it is also possible to design the system in a way that it actually comes with some disadvantages if calls are not marked in a reasonable timeframe. For instance, all the incoming call from that number is blocked if it is not marked within three days. I'm just providing a broad idea, and I'm pretty sure there are different types of details that can make it more workable.
