现在正在给小孩申请CCB,centerlink说要4-6周才能批下来,但我们又希望一周后就送孩子去幼儿园,问了幼儿园,说要先交全费,等CCB批了,交GAP就行,但我看centerlink的申请表上写: Child care benefit my be backdated up to 28 days if the child care benefit approved child care service provider reports that your child attended during this period. 是不是让幼儿园写个报告证明这段时间我们已经上幼儿园,多交的钱能够退给我们,是幼儿园退给我们还是centerlink退给我们,有经历过的朋友们?
