Gucci bag offered as original but fake?

Dear Sir or Madam, I have a concern: I purchased a Gucci shoulder bag last week and paid via PayPal, unfortunately under the Friends and Family account. The package arrived today, and I immediately realized it was a fake.

The facts: The bag was explicitly advertised as original, and it was also confirmed in correspondence that it was original! I confronted him, and he emphasized that he had bought it himself and had no idea. Now, all of a sudden, he was unsure whether it was actually original. I paid 300 hard-earned euros only to end up with a fake bag that cost 40 euros. Annoying. I've written an email to the classifieds. I'll definitely be going to a lawyer. My question to you: What are my chances of getting my money back? Or does anyone have experience with something similar? Thank you for your attention and time! Best regards
