What should I do if I made a P2P payment mistake when buying crypto?

If you overpay, contact the merchant to request a refund if the crypto hasn’t been released, or submit a dispute if the crypto has already been released. If you underpay, contact the merchant to make a supplementary payment. If you paid to the wrong account, coordinate with the merchant to release the crypto if they received the funds, or contact OKX Assistant.
