7.4. When Customer receives a payment through the Service, he/she is NOT protected against a subsequent reversal of the transaction. Examples of such a reversal include, but are not limited to, a credit card reversal by the sender of the payment and a reversal of the transaction because the sender of the payment was using a stolen credit card or unauthorised bank account.
