Problem via apay is... its fetching only 6 months bill. So no 5% rebate. I tried paying 1 year amount(with 5% rebate) via apay balance but it somehow failed & got refund.
So was thinking if I should try the same by changing amount I pay (with 5% rebate for 1 year instead of auto generated 6 months) and pay with apay card or should directly pay on CMDA website.
