TrenItalia review: Customer service despicable

Purchased tickets online Paris - Lyon on Trenitalia.
I called customer service to inform them I chose the wrong station (Lyon Airport rather than city center). The agent basically was yelling in my ear, saying there is nothing they can do, that it's my fault, that I should lodge a complaint online. Although my tone was courteous and just asking for a solution, the agent kept yelling at me, and saying it's my fault and there is nothing they can do. When they told me the only thing I can do is lodge a complaint, I tried telling her I am looking for a solution, but she just hung up on me. I will never travel trenitalia again, because that is the abomination of customer service, although there was no aggressiveness or accusation on my part.
