Nationwide chargeback help

Futuristic

The merchant in this case "bmboption" provided proof to Nationwide you received what you paid for hence they won the appeal. You should be able to re-appeal if you gather some proof it's a common trading scam.

Ask Nationwide for a payment plan to repay the money (to avoid standard interest) while you appeal/go through FOS/otherwise complain in order to reclaim your funds.
