Delated Facebook picture still appears on Google

I've delated a picture from my Facebook business page one month ago. It's still visible on Google. Google tells me that they can't do anything about it, and Facebook too (I have already contacted them both). What should I do?
NB: My business' name is "Scrivimi un biscotto" and the picture that I talk about shows "Parola di Biscotto" (which is the previous name of my business). Thank you in advance
