How do you collect proof, and how do you handle the money going the other way?
Proof is collected at the moment of result, not asked for at the end. The measure is the share of winners who give a testimonial, a success interview or a Trustpilot review: every third at least, every second is good, some offers reach 70%. Refunds get a call first, a fair decision, and a fast payout. Chargebacks are usually a sales problem.
