I sent a payment to recipient bc1qr06w3lxxv5chvgyr54z957324dgels2g5fa0jcAnd it is confirmed. However, they are claiming they haven’t received it and said I should resend the amount and I will get the initial payment back.How can I tell if they actually received it?If I send a duplicate amount, how will I get my original payment refunded?Is this a scam?
