[UK] Loan groups scam

I joined a loan group because I genuinely needed help. One of the group owners told me they would lend me money. As payment, I sent them a gift card, but after they received the code, they kept it and never sent me the loan.

The worst part is that I can't even warn other people in the group because the person who scammed me is one of the owners. If I try to post about what happened, they'll probably delete my post or ban me from the group.

I have screenshots of our entire conversation, including everything that was said and sent. I have proof of everything that happened. Despite everything I was promised, I never received a single cent from this person. They took my gift card and never sent me the loan.

I'm really disappointed by this experience. I'm sharing this to warn others because I don't want anyone else to go through the same thing.
