True.
My experience when I first started using FB was an offer to buy a Honda Generator at a great price.
I sent my payment using a credit card on Paypal and never received the generator.
I contacted Paypal. After 2 weeks they said the seller had a receipt for delivery from the USPS that it had been delivered to my mailbox.
I asked how they got a generator into a mail kiosk and it was an obvious fake receipt?
Paypal never refunded the money.
I contacted the credit card company and got the same response.
I complained to the cc company that I was a senior citizen that had been defrauded by FB, Paypal, and now my cc company.
I got an immediate refund from the cc company.
Colorado's AG at the time was really tough on crimes against anyone over 65, considered a senior citizen and at risk of fraud.
