Marketplace scam on Facebook

Interested buyers call about products on Facebook Marketplace, claim they are not in the city, and send a delivery person to pick up the item. They pay via transfer to Nequi or Bancolombia, send screenshots of the payments, but upon verification, the money never arrives. Meanwhile, they block the account to deceive the seller by claiming the payment has already been made, and the delivery person (an accomplice) appears rushed and has no time to wait. Whoever hands over the merchandise loses it. Be very careful.
