Answer:
Better Business Bureau
Step-by-step explanation:
Jared's options are very limited, and by contacting the Better Business Bureau (BBB) he would basically be filing a complaint that is public and anyone in North America can access. The BBB cannot do anything to make Green Gardens actually return the money to Jared or even fix his garden, but by making the complaint public, Jared is applying public pressure to the company in order for them to respond in a favorable way.
Jared's problem may or may not be solved, but at least the stain in Green Gardens's reputation will remain.
