Since BDO in SM Malls are open up to 4 p.m. during Saturdays and Sundays, you may still use the 24/7 Automated LoadWallet Replenishment even you don't have any Smart Money Account. Just use their payment slip and fill up the portions like the picture below. Then follow the syntax (SMS format in verifying your deposit).

Take note: Verify your deposit, 20 min. to 1 hour after the payment because BDO might have a transaction delays.
