i never gave facebook,com any permission to take 5.00 dollars from my debit card.i want my money back.

I have been charged 4 times for some bogus item on facebook. My husband put our household account on file, now we are being charged over and over with fees and overages. It has to stop yesterday. I will be contacting my Bank to change my account. I need a refund and a correction with my financial institution.
