Just wondering, if we topup today RM30, our account has 30 days validity. Say, the next hour we share-a-topup (SAT) to another Hotlink number, what happen to our existing 30 days validity? Maintained or deducted 5 days? Hotlink should remove that RM0.50 fee for every SAT activity. Or at least limit the activity to once a week and then start charging 50 Sen.
