Hmm. Such cynicism is...a bit daunting in one so young.
It is the nature of society that not all of us can do everything for ourselves and that we must therefore occasionally turn to others to perform certain services for us. Grocery stores. Utility companies. Gas stations. Sandwich shops (although I would argue that having someone make your sandwich for you is not a necessity for most of us). While scam artists may get away with it for a while, eventually their business will suffer because of their unscrupulous practices.
But you're not the one with the issue, so I'm kind of preaching to the choir.
