What does the ending of the story named a letter to god tell about Lincho​

This question seems to be incomplete. However, there is enough information to find the right answer.

In the end, Lencho​ seems to be ungrateful and even accuses the people from the post office of having stolen his money, because he´s unaware that it was them, and not God, who gave him money.

Explanation:

In the story "A Letter to God," by G.L. Fuentes, Lencho is a farmer whose entire crop yield has been damaged by a hailstorm and decides to write a letter to God asking for 100 pesos to sow his field again. When the postmaster discovers Lencho´s letter, secretly collects some money for him, but is not the full amount Lencho had asked for. In the end, Lencho writes another letter for God, asking for the full amount, and accusing the people from the post office of having stolen part of his money, showing that he´s ungrateful and unaware of who are the people actually trying to help him.
