According to the Philippine Charity Sweepstakes Office (PCSO), it's important to keep in mind that once you've made a bet, you won't be able to request a refund. Therefore, it's crucial to thoroughly review all the details of your 3D lotto ticket, including the type of bet, the amount you're betting, the date, and the numbers you've selected, before confirming your purchase. This way, you can ensure that all the information is accurate and avoid any issues later on.
