Facebook Scammers

I block all unknown calls and numbers that I don't know..Facebook has a lot of scams too. The scammers sell fake products via Facebook and they use AI to generate their products. I was scammed via facebook advertisement...I purchased a car battery charger, It was an American company. They kept taking money from bank account. They said I had subscribed their account and I can only get out of it in 12 months. I had to close the account and open another account.
